Renovation Timelines 2026: A Step-by-Step Schedule | Mudelar

As a technical lead at Mudelar, I’ve overseen hundreds of residential renovations across Porto and northern Portugal. The most common question I hear from clients, especially expats, isn't about cost, but time. "How long will it *really* take?" is the first thing on everyone's mind. The uncertainty of living in a construction zone or paying for two homes at once can be daunting. That's why understanding realistic renovation timelines is crucial for a smooth and successful project. In this guide, I will pull back the curtain on the entire process, sharing a detailed, step-by-step schedule based on our on-the-ground experience. You will learn about each phase, from initial design to the final handover, and the factors that can speed up or slow down your project in Portugal.

Quick summary

• Planning is king: The initial design, planning, and material selection phase can take 2-6 weeks and is fundamental to avoiding delays later.
• Permits are the big variable: Obtaining the correct municipal license (*licença*) in Portugal is often the longest phase, ranging from 4 weeks for a simple *Comunicação Prévia* to over 4 months for a full *Licenciamento*.
• Demolition is quick, but crucial: The 'dirty work' of stripping back an apartment or house usually takes 1-3 weeks, including first-fix plumbing and electrical work.
• Construction is the core phase: Building walls, laying floors, and installing kitchens and bathrooms is the main event, typically lasting 4-10 weeks depending on complexity.
• Finishes require precision: The final 2-4 weeks are for painting, carpentry, light fittings, and addressing any small imperfections (snagging).
• Buffer time is essential: I always advise clients to add a 15-20% time buffer to the schedule to account for unforeseen issues or supply chain delays.
• A turnkey partner saves time: Working with a company like Mudelar streamlines the entire process, managing architects, builders, and नगर परिषद (*câmara municipal*) communications for you.

Understanding the Phases of a Renovation Project

A common misconception is that a renovation begins when the first wall comes down. In reality, the physical work is just one part of a much larger process. A well-managed renovation is a sequence of carefully coordinated phases. Missing or rushing a step early on will almost certainly cause costly delays later. At Mudelar, we break every project, whether in Lisbon's historic districts or a villa in Cascais, into a clear, linear progression. This ensures that materials arrive on time, specialist tradespeople aren't tripping over each other, and the project flows smoothly.

The main phases are Planning & Design, where your vision is translated into technical drawings; Licensing & Permits, the bureaucratic step of getting approval from the local council; Demolition & Preparation, the stripping out of the old; Construction & Installation, the building back up of the new space; Finishing, where the aesthetic details are applied; and finally, Handover & Snagging, where the project is completed and signed off. Understanding this sequence is the first step towards creating a realistic renovation timeline.

Phase 1: Planning, Design, and Budgeting (2-6 Weeks)

This is arguably the most important phase of your entire renovation. Time spent here is an investment that pays dividends in efficiency later. This is where you and your chosen team—be it an architect, a designer, or a turnkey company like Mudelar—define the project's scope, create the architectural plans, and make crucial decisions about materials and finishes. Rushing this stage often leads to changes mid-project, which are the number one cause of budget and timeline overruns. We dedicate significant time here to ensure the client is 100% confident before a single hammer is swung.

Architectural & Engineering Plans

During this stage, your initial ideas are turned into detailed technical drawings. These aren't just simple floor plans; they include electrical layouts, plumbing schematics, structural engineering calculations (if you're moving load-bearing walls), and detailed specifications for every element of the build. For a full apartment renovation, this process typically takes our team and our partner architects about 2-3 weeks. These plans are the blueprint for the entire project and are non-negotiable for obtaining permits and getting accurate quotes from suppliers.

Material Selection & Sourcing

While plans are being drawn, we guide our clients through selecting all their materials. This includes everything from flooring (like AC5 laminate or rectified porcelain tile), to kitchen cabinetry (from brands like Egger or Kronospan), countertops (like Silestone or Compac engineered quartz), bathroom fixtures (from Grohe, Roca, or Sanindusa), paint colours, and light fixtures. Finalising these choices early is critical. Many high-quality materials, especially custom items or imported tiles, can have lead times of 4-8 weeks. By ordering them during the planning or licensing phase, we ensure they are on-site exactly when the construction team needs them, preventing idle time.

Phase 2: Licensing and Permits (4-16+ Weeks)

Welcome to the most unpredictable part of any renovation timeline in Portugal. Navigating the municipal licensing process requires patience, experience, and local knowledge. The timeline depends entirely on the scope of your work and the specific requirements of your local *câmara municipal* (city council). Work inside an apartment that doesn't change the layout, facade, or structure might not need a formal license. However, most significant renovations do.

There are two main routes. The *Comunicação Prévia* is a faster process for projects that comply with existing municipal plans. You submit the full architectural and engineering plans, and if the council doesn't raise objections within a set period (typically 20-30 working days), you can begin work after paying the required fees. The second, more involved route is a full *Licenciamento*. This is required for projects that alter the building's structure, change its use (e.g., residential to commercial), or deviate from the municipal plan. This is a multi-stage approval process that can easily take 4-8 months or more, especially in busy councils like Lisbon or Porto. Our team has extensive experience navigating these processes in Braga, Setúbal, and Aveiro, which helps to minimize delays.

Phase 3: The "Dirty Work" - Demolition and Preparation (1-3 Weeks)

Once the license is granted and the project has a start date, things finally start moving on-site. This phase is noisy, dusty, and dramatic, but relatively quick. The goal is to strip the property back to a 'clean slate' ready for the new installation. This includes tearing down non-structural walls as per the new plans, removing old flooring, stripping out old kitchens and bathrooms, and taking out old plumbing and wiring. Protecting communal areas like building entrances and lifts is a priority for us during this phase.

Demolition and Waste Removal

This step typically takes about 1 week for a standard T2 or T3 apartment (70-120m²). All debris is carefully removed and disposed of at certified waste facilities, following all environmental regulations. This is a critical step, and we always ensure the site is left clean and safe, ready for the specialised trades to come in. Proper site preparation during demolition prevents issues down the line.

First-Fix Electrics and Plumbing

With the walls and floors exposed, it's the perfect time for the 'first fix' or rough-in stage. Plumbers will run new water supply and waste pipes to the exact locations for the new kitchen and bathroom layouts. Electricians will chase walls to run new conduits and install back-boxes for sockets, switches, and lighting points as specified in the electrical plan. This stage is crucial for getting the infrastructure right. It usually takes another 1-2 weeks and must be completed before any new walls are closed up.

Phase 4: Construction and Installation (4-10 Weeks)

This is the longest and most transformative phase, where your new home begins to take shape. It's a carefully choreographed sequence of different trades working together. The duration heavily depends on the scale and complexity of the project. A simple cosmetic update might be on the lower end, while a full gut renovation with bespoke carpentry will be at the higher end of this range.

Walls, Plastering, and Flooring

With pipes and wires in place, new partition walls (typically plasterboard on a metal frame) are built. The next step is plastering all the walls and ceilings to create a smooth, perfect surface for painting. This is a skilled job and requires drying time—a factor often overlooked in DIY timelines. Once the plaster is dry, the team can install sub-floors if needed, followed by the final flooring material. Installing rectified porcelain tile requires more precision and time than floating laminate flooring. This entire sequence can take 2-4 weeks.

Kitchen and Bathroom Installation

This is a milestone in any renovation. The installation of the kitchen cabinets, followed by the countertop templating and fitting, usually takes about a week. While the stone for the countertop is being cut (which can take 5-10 working days), work can continue elsewhere. In the bathrooms, the team will waterproof the shower areas (a critical step!), install shower trays or baths, and begin tiling the walls and floors. Once the tiling is complete and has set, the toilets, vanities, and taps from brands like Roca or Sanindusa are installed. This multi-step process for bathrooms typically takes 1-2 weeks per bathroom.

Phase 5: Finishes and Final Touches (2-4 Weeks)

The end is in sight! This phase is all about the details that make a house a home. While less structurally complex, it requires a high level of skill and attention to detail. It's often called the 'second fix' phase. The property, which has been a dusty construction site, is transformed into a clean, liveable space. It's a very rewarding stage for both our team and the clients.

Painting and Carpentry

With all the major construction done, the painters arrive. They will prepare all surfaces and apply the primer and final coats of paint. This usually takes about 1-2 weeks for a full apartment, allowing for drying time between coats. Simultaneously, our carpenters will be on-site installing interior doors, skirting boards, architraves, and any custom-built wardrobes or shelving units. The final pieces, like door handles and cabinet pulls, are fitted now.

Final Inspections and Snagging

During the last week, the 'second-fix' electrics are completed: sockets, switches, and light fixtures are installed and connected. Plumbers will connect sinks and appliances like washing machines. The entire property is then given a deep, professional clean. After this, our project manager conducts a thorough inspection with the client, creating a 'snag list' of any minor imperfections—a paint drip, a misaligned handle, a sticky door. Correcting these snags usually takes a few days, ensuring the final product meets the high standards we promise at Mudelar before the official handover.

Factors That Influence Your Renovation Timeline

Not all renovations are created equal. Several key factors can significantly impact the overall renovation timeline:

1. Project Scope and Size: A small bathroom refresh will be much faster than a full 150m² apartment gut renovation.
2. Complexity: Moving structural walls, adding a bathroom, or complex custom carpentry will add weeks or months to the schedule.
3. Property Type and Age: Renovating a historic building in Porto's Baixa area often uncovers surprises (uneven floors, crumbling walls) and may have stricter heritage regulations, adding time compared to a modern apartment in Oeiras.
4. Permit Requirements: As discussed, a *Licenciamento* adds months to the pre-construction phase compared to a *Comunicação Prévia*.
5. Client Decision-Making: Delays in choosing tiles, paint colours, or fixtures can bring the entire project to a halt. Decisiveness is key!
6. Material Availability: Bespoke items or materials imported from outside the EU can have long lead times. Supply chain disruptions can also cause unexpected delays.
7. Weather (for exterior work): Painting facades or roof work is dependent on dry weather, which can be a factor in Portugal's winter months.

How much does it cost? Indicative prices in Portugal (2026)

While this article focuses on timelines, it's useful to see how cost and duration are linked. More extensive renovations take longer and naturally cost more. Here's a table showing typical renovation types with their associated costs per square meter and estimated timelines.

*Note: Timelines do not include the pre-construction licensing phase, which can add 1-6 months.*

Quick comparison

Understanding the permitting process is critical for timeline planning in Portugal. Here is a comparison of the two most common licensing paths.

Common mistakes to avoid

Over the years, I’ve seen the same issues trip people up and delay their projects. Here are the most common mistakes to avoid for a smoother renovation:

1. Starting work without a 100% final plan. Making changes once demolition has begun is the single biggest cause of delays and cost increases. Lock in your design and material choices first.
2. Underestimating the permit timeline. Many people assume they can get a license in a few weeks. In reality, even a 'simple' permit in Lisbon or Porto can take months. Always factor this into your schedule.
3. Not ordering materials with long lead times early. That beautiful Italian tile or custom-made window can take 10-12 weeks to arrive. If you wait until the week before, your project will grind to a halt.
4. Living in the property during a major renovation. It's incredibly stressful, unhealthy due to dust, and slows down the workers who have to clean up every day. Plan for alternative accommodation.
5. Choosing a contractor based on the cheapest price alone. A quote that seems too good to be true often is. It could mean they use subpar materials, cut corners, or will add extra charges later. Verify references and look for value, not just a low price.
6. Failing to budget for a contingency. Unforeseen problems always arise in renovations. I recommend a 15-20% contingency fund and adding a similar buffer to your timeline to manage surprises without stress.
7. Crowding the schedule. Trying to have painters, electricians, and carpenters on-site at the same time to 'speed things up' is counterproductive. It leads to mistakes, damages, and ultimately, delays.

Pre-project checklist

Before you even contact a renovation company, getting organized will make the entire process smoother. Here is a checklist to work through:

• [ ] Define your total budget: Know your absolute maximum, including a 15-20% contingency fund.
• [ ] Create a wish list: Separate 'must-haves' (e.g., a second bathroom) from 'nice-to-haves' (e.g., underfloor heating).
• [ ] Gather inspiration: Create a mood board on Pinterest or save images of styles, materials, and layouts you love.
• [ ] Understand your property's legal status: Find the property's plans (*plantas*) and title deed (*caderneta predial*).
• [ ] Check local regulations: A quick look at your area's *PDM (Plano Diretor Municipal)* online can give clues about what is and isn't allowed.
• [ ] Decide on your living situation: Will you move out? If so, when and for how long? Factor this cost into your budget.
• [ ] Interview potential partners: Talk to at least two or three architects, designers, or turnkey companies.
• [ ] Prepare a list of questions: Use this article as a guide to ask them about their process, timelines, and how they handle delays.

Frequently asked questions (FAQ)

How long does a full apartment renovation take in Lisbon?

A full gut renovation of a standard T2 (80-100m²) apartment in Lisbon, once licenses are approved, typically takes between 12 to 18 weeks. This includes demolition, new electrical and plumbing, new walls, kitchen, bathrooms, flooring, and painting. Timelines can be longer in older buildings (*prédios pombalinos*) which may require more structural care and present unforeseen challenges.

Do I need a permit to renovate my kitchen in Portugal?

It depends. If you are simply replacing cabinets, countertops, and appliances in the same location without moving walls or altering plumbing/electrical points significantly, you generally do not need a permit (*licença de obras*). However, if you are moving the kitchen to another room, knocking down a wall to create an open-plan space, or changing windows, you will almost certainly need to submit a *Comunicação Prévia* to the council.

What is the most time-consuming part of a renovation?

Before construction starts, the licensing and permitting phase is almost always the longest and most unpredictable part, often taking several months. During the construction phase itself, the plastering and tiling stages often require the most time, as they involve multiple steps and necessary drying or curing times that cannot be rushed without compromising quality.

How can I speed up my renovation?

The best way to speed up your renovation is to be prepared and decisive. Have all your plans finalized and materials chosen before work begins. Work with a professional turnkey company that can manage the project efficiently. Avoid making changes mid-project. A clear plan, executed by a professional team, is the fastest route to a finished home.

How long does it take to get a building license in Porto?

Timelines in Porto are similar to Lisbon. For a *Comunicação Prévia* on an apartment renovation, expect a 4-8 week process. For a full *Licenciamento* that involves structural or facade changes, the timeline is realistically 6-12 months or more, depending on the complexity and the workload of the *Câmara Municipal do Porto* at that time.

What's the difference between renovating a house and an apartment?

House renovations often have a longer timeline as they are typically larger and may involve exterior work (roofing, facade painting, landscaping), which is weather-dependent. They can also have more complex structural elements. Apartment renovations are more constrained by building rules, access for materials, and noise restrictions for neighbours, which requires careful logistical planning.

How much buffer time should I add to my renovation schedule?

As a rule of thumb, I always advise adding a 15-20% time contingency to the construction schedule. For a project estimated to take 12 weeks, you should realistically budget for 14-15 weeks. This buffer provides a cushion for unforeseen discoveries (like asbestos or a leaky pipe), supply chain delays, or other small issues without causing major stress.

Is it realistic to renovate a bathroom in 2 weeks?

While TV shows might suggest it's possible, a high-quality bathroom renovation in 2 weeks is extremely ambitious and risky. A proper job involves demolition, potential plumbing changes, waterproofing (which needs to cure), tiling (which needs to set), plastering, and installation. A more realistic and safe timeline for a standard bathroom from start to finish is 3-4 weeks to ensure quality and longevity.

Conclusion

Understanding and planning for realistic renovation timelines is the foundation of a successful project. It's not about speed at all costs; it's about efficient, logical sequencing to ensure a high-quality result without unnecessary delays or stress. From the crucial initial planning and tedious but essential licensing, through to the dust of demolition and the precision of the final finishes, each phase has its own timeline. By anticipating these steps, being decisive with choices, and working with an experienced team, you can navigate your renovation with confidence.
