"The team from Casa das Janelas were great to work with from start to finish; utterly professional and very nice too. They always came when they said they would, made excellent recommendations for solutions, completed the work to the timescale and cost they'd indicated, and went away leaving everything beautifully tidy! I will certainly be contacting them again about future work. Deirdre Tinney"

"Thank you for the completed works. My husband and I appreciate all your work. I´ve not seen the mosquito screens yet but my husband is happy. Kind regards, Nuala"


"Exceptional service from start to finish! Highly recommended. Casa das Janelas replaced all our windows and doors and we couldn't be happier. From the offset, Nuno was very professional answering all questions, responding to emails within an hour and going through in detail the pre sales quote and installation process. Which were a lot cheaper than others we had received!! On the day of fitting, the team arrived early, were courteous throughout, and their attention to detail was simply outstanding. The windows and doors are of high quality, beautifully fitted and the making good around the frame, amazing.Our expectations were far exceeded and we wouldn't hesitate in recommending to others. This was all carried out throughout a global pandemic! Thank you for transforming our home! Claire Hill"

Claire Hill

"Excellent job. Great Professionalism in Pre-Sales to recommend the best solution, seriousness in budgeting, delivery deadlines perfectly completed in time, and the technicians who installed the windows and doors properly aware of the work they were doing. Recommend this company."

José Fernandes

"Thanks Nuno and Marco for your great service, efficient communication, creativity and outside of the box thinking! We love our windows and patio doors and the gris agate color of the outside frames, it was a challenge to find it, but you managed to find it for us! The color really matches perfectly the exterior of our traditonal quinta! We definitely recommend you guys."

Sascha Bauer

"Hi Marco and Nuno The fitters have just left the house. I must say how pleased we are with the end result and what a fantastic team you have. They were hardworking and helpful and very careful in our house. They take pride in their work (unusual these days). The quality and look of the windows is fantastic and impossible to tell the difference from the originals. Thank you so much. Best Terry"


"Excellent professionals. From punctuality, quality of service, availability and meeting our needs. I recommend today and always!!!"

Rodrigo Leitão - Matilde Leitão

"Thank you for the professional service you provided. I really recommend you based on smooth communication, quick delivery and all devoted staff."


"Extremely professional, fast and quite simply perfect. We had a weird shape door, in the historic centre and these chaps made a door which fitted perfectly with the traditional style, while keeping modern isolating qualities. It was fitted extremely well, no gaps, everything uniform. Not easy in such an old house. Highly recommended. "

Peter Van Meerem

"From first contact to the final fitting of a new front door we got excellent service from Marco and his team. Professional but friendly, efficient and importantly tradesmen who were very tidy made the whole process painless. The quality of the door is first class and we have no hesitation in recommending Casa das Janelas. Sally MacAdie"

Sally MacAdie

"We are extremely happy with our windows and doors and with the service from Vasili and Tiago (as well as Marco and Nuno of course). We can already feel the difference in the house and we’re sure it will make a big difference in the colder months."

Jane Houston

"Marco & Nuno at Casa das Janelas are great to work with. They’re exceptionally responsive and were very understanding when it came to figuring out what we needed when replacing our front door. We love our new door which was installed on time and at the price that was quoted. The actual installation went very smoothly and the door looks like it was part of the original construction. We highly recommend using Casa das Janelas. David & Gilly"
