Signs It's Time for Window Replacement

Westport’s coastal air can shorten the lifespan of windows. Watch for these signs it’s time to replace:

  • Drafts: Noticeable air leaks let in cold winter air and summer humidity, reducing comfort and straining your HVAC system.
  • Difficult to Open or Close: Salt air and moisture can cause frames to swell or hardware to corrode, making operation difficult or unsafe.
  • Window Condensation: Persistent fog or moisture between panes is a clear sign of failed seals and compromised efficiency.
  • Fading Interior Furnishings: Prolonged sun exposure can bleach flooring, fabrics, and furniture.

After considering 3 quotes for replacing 11 windows in our mobile home, we chose Couto Construction. We wanted a quality product, good workmanship and reasonable pricing ( hard to find today) the quality of the windows is outstanding and we are very pleased with how they look, not only on the inside, but the outside as well with our siding neatly replaced & very attractive window trim. The whole transaction with Couto was outstanding -from the sales rep ( Sean) who was so polite, respectful & informative, to the office staff ( again so pleasant & helpful) to the installers .(Logan & Andrew ) who were extremely talented & meticulous with the installation of the windows. They explained everything they were doing & why, asked me if I had any questions, constantly checked with me to make sure I was comfortable with virtually ever step or adjustment, etc. I simply can Not convey how polite & professional EVERY SINGLE PERSON was, that I had. contact with. The supplies were delivered & neatly stored in the back yard, before setting up the outside work station, we were asked permission for the area we preferred, ALL debris was cleared away EVERY day-both inside and outside -including vacuuming the floors. They truly were amazing, and their workmanship top notch professional. Again, I can't say enough how pleasant, polite & helpful the entire staff was, and what an enjoyable experience it was. The project manager (Carlos) even came to check on the progress-so helpful & patient & informative! I would highly recommend this company to anyone needing ANY kind of work-I know I certainly will in the future & im soooo glad I found them. Oh, I almost forgot -of the 3 estimates -theirs was the best product, best value & best price too. JACKPOT!!!!

All employees exemplified professionalism, integrity, and teamwork. High quality of work done at competitive pricing. The Project Manager Manny Leandres was in constant contact with me during the entire planning and construction process. Manny Leandres was available any time I had a question and was prompt and accurate in his response. Definitely will be doing business with Couto Construction in the future.

Brendan and Josimer did an excellent job of installing a pair of picture windows. They were neat, thorough and courteous through the project. Cleaned up after they were finished and reiterated that if any problems should occur, just call and they would come back right away to resolve them. Don't expect any problems though. Would use them again

Caesar and his team showed up very early on 7/5/21 to complete the roof installation. They worked almost a 10 hour day and returned a few days later to complete one last minimal task. I commend them that they kept the environment clean. I have dogs so I was worried about nails and other materials in the backyard however did not run into any issues. Caesar came back about a week later to pick up any left over materials from the driveway and left a voicemail letting me know. He was always responsive when I called or texted him and I appreciated that. Would highly recommend this company if you need your roof repaired or redone. I had interviewed 3 other companies before Couto and when John B came out to the home and completed his assessment of our needs, it was the most accurate and made the most sense so I had to go with them. The price was the highest however quality, warranty, and again a thorough assessment was the reason I chose this company. I'm just waiting to hear back from John about my promised restaurant gift card now haha Thank you guys for the great work!

Caesar and Justin did a masterful job of dissembling an old support column on our front porch and the installing a new fiberglass column to match the existing original three. It was important to get it just right and they did.
