We design, manufacture and install windows, doors, sliding systems and partitions. These are reviews of the projects we completed, written by the people who saw the whole process through. We publish them all, including those that point out what we can do better.

We replaced all the joinery in a house in Cascais with Aluprof MB-79N aluminium. The quote was itemised opening by opening, with no extras appearing later. What struck me most was the surveying: they came twice to confirm the openings before going into production. The work was finished in two days and the difference in street noise is obvious.
Very happy with SKLO’s work. Frederico helped us choose the PVC windows for our flat in Setúbal and recommended the Naturo 80 HST sliding doors for the terrace, which glide with remarkable ease despite their size. We also appreciated the Swisspacer spacers in the double glazing — we can already feel the difference in insulation. Everything went smoothly and the installation was quick and clean.
We wanted a large opening onto the garden without heavy visible profiles, and the team proposed the Naturo 80 HST in timber. They explained the weight and width limits before we committed, which gave us confidence. The door slides with one finger and the oak finish came out exactly as it looked on the showroom sample.
SKLO installed 9 Meranti timber windows with double glazing at our house in Sintra, in a custom dark finish. Vadym ran the project and what stood out most was how everything was managed even when we were not always on site: clear, timely information about surveys, production and installation dates.
A flat in Almada, six windows in Energeto Neo with triple glazing. I asked for three quotes and SKLO was not the cheapest, but it was the only one that gave Uw figures per opening and explained the glazing choice. Clean installation, with floor protection and debris removed the same day.
We chose SKLO for our house in the Algarve: 7 Meranti timber windows, double glazed, dark grey outside and white inside. The project was managed by Yurii, who guided us through every stage from surveys to final installation. The measurements were very precise and they explained everything, particularly how timber behaves in strong sun and coastal humidity. Installation was planned around the weather and completed quickly and cleanly. At the end we were given clear maintenance instructions.
We needed to divide an open-plan space in Lisbon without losing daylight. They surveyed with the office still running and installed the partitions on a Saturday so the team would not stop. The acoustic separation between rooms is better than we expected for plain laminated glass.
My experience with this company was excellent, from first contact through to the installation of the Aluprof MB-60 windows. Beyond the quality of the material, the fitters were extremely friendly, helpful and did a five-star job.
The product is very good — Naturo 68 timber with an immaculate finish — but production ran about two weeks behind the date first given. They warned me in advance and explained why, which I appreciate, though it meant rescheduling the painter. The installation itself was precise and the team left everything clean.
We had a problem with the survey, as the technician arrived almost an hour late — but the measurements were taken correctly and there were no problems afterwards. I asked that the old windows only be removed once the new ones were ready, and that request was respected. The installation was careful; the facade paintwork was slightly damaged but repaired on the spot. The whole process took more than 15 days, longer than I expected, but within the contract deadlines. Communication at every stage was good, polite and professional. The windows and interior partitions for our office in Torres Vedras came out correct and efficient.
We bought an old house in Ericeira and wanted to keep the character of the timber windows but with modern performance. SKLO reproduced the original divisions in Esperia Life 80 and advised us on maintenance close to the sea. All communication was in English whenever I needed it, without any difficulty.
I am very pleased with the service: from the speed to the friendliness of the workers, everything was excellent. I recommend them to anyone who needs to change the windows in their home — an outstanding service.
They installed a front door with an RC2 panel in Setúbal. They showed me the profile section and the locks in the showroom before I decided, which made it much easier to compare with what other companies offered. It sits perfectly aligned and closes without effort.
The deadline was met, the price was the lowest of all the quotes we had asked for, and the result could not have been better. The five stars were earned by the work done and by how pleasant they were.
A loft project in Lisbon with Forster Unico steel joinery. It is a demanding system and SKLO was the only company that immediately understood the architect’s drawing, including the slim profiles in the interior partitions. The final result is exactly what was designed.
I am very satisfied with the work carried out. They were highly professional and careful from start to finish. We opted for the Aluplast PVC windows and it was the best decision — the quality is very good.
I bought 5 energy class A+ windows at a very competitive price. From quoting, surveying and ordering through to installation, everything went quickly, cordially and transparently. A special word for how clean they left the site when the fitting was done.
A commercial project in Porto with a CW 50 facade. They worked well with our main contractor, delivered the shop drawings on time and resolved a structural clash on site without delaying the programme. I would hire them again for larger-scale projects.
I was very satisfied with the work provided and with the customer service. Always available to help and to make sure the customer is happy.
I decided to have my windows renovated. I want to thank them for the service and congratulate the fitters who installed the new windows. I am pleased with the quality of both the service and the windows.
Renovation of a house in Torres Vedras, eight windows in Cortizo A70 with external shutters. All the information was sent in writing, with clear deadlines and conditions. The fitting took two days and they sealed all the junctions properly — no leaks through the first winter.
I have nothing but good things to say about this company, from first contact through to the window installation. Not to mention the windows themselves — the material is first rate. The lads who fitted them were extremely friendly, extremely helpful and did a 5-star job.
Pleased with the product and very pleased with the installation: highly professional, with attention to detail. Many thanks for the service. Recommended.
Spectacular service! A 5+ experience, very helpful throughout the selection process, excellent installation and quality material. Well worth it and highly recommended.
An excellent company. Outstanding service and support.
Incredible service. They came twice: first to measure the windows and make sure the dimensions were right, and then to install the Reynaers SL 38 joinery. The service was top marks. They were very helpful throughout the selection process, the installation was excellent and the material used is high quality. It was a choice well worth making and I recommend them highly.
