Benefits of Installing New Windows

New windows can make a noticeable difference in Onset homes, where older units often struggle with drafts, corrosion, and moisture intrusion.

  • Energy Efficiency: Modern insulated glass reduces air leakage and helps regulate indoor temperatures despite coastal winds. 
  • Improved Comfort: New windows minimize drafts and cold spots, especially in rooms facing the shoreline. 
  • Noise Reduction: Upgraded windows help soften exterior sounds from nearby beaches, marinas, and seasonal activity. 
  • Enhanced Appearance: Clean window lines and updated frames refresh seaside exteriors while maintaining neighborhood character. 
  • Better Home Value: Energy-efficient, well-installed windows increase buyer confidence and long-term property value.

Signs It's Time for Window Replacement

Coastal exposure accelerates window wear, making these warning signs especially common in Onset homes.

  • Drafts or High Heating Bills: Failing seals allow wind-driven air infiltration that drives up heating costs.  
  • Condensation Between Panes: Fogging inside the glass indicates seal failure and reduced insulating performance.  
  • Tough Operation: Salt air and moisture can corrode hardware, making windows difficult to open or close. 
  • Cracked or Rusted Frames: Extended exposure to moisture can break down finishes and structural components.  
  • Faded Interiors: Older windows allow UV rays to fade floors, furniture, and interior finishes.

I called Couto construction for a quote on a new roof and was amazed at how well organized they were and fast. I had called three different companies and they were the only ones to respond and on a Saturday too. The people that answered were both polite and professional, we arranged a meeting the following week and they double checked the day before that I was going to be there. Nick was the estimator and he showed up on time, was very professional and gave us a reasonable quote after walking us through everything that was going to be done. We agreed on the price and two weeks later we had a new roof. The crew was amazing. Richie was the supervisor and he walked me around explaining how it was going to go. The owner showed up and checked in on everything. They were super fast and after two days it was all cleaned up like they had never been there. We did an underlay that looked fantastic the first day and the shingle/trim and gutters the second. It looks great and worth every penny. Next year we're going with them to do the windows. Thanks guys! Great job!

Brendan & Mark installed gutter covers. Their work was excellent, carried out in a very professional manner. I was kept well informed about the job. They both were very courteous & I would have no hesitation in recommending them & Couto Construction for future projects I may have. My dealings with both office personnel & sales representative Nick were also excellent, well accommodating my needs.

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.
