Low-Maintenance Trex Decking for Dorchester Homes
Wouldn’t it be great to have a welcoming spot to relax in your own backyard? Whereas traditional decks offer comfort at the expense of high maintenance, Trex decking does it all! This wood-alternative composite mimics natural materials but won’t warp, blister, or rot—saving you time and money on maintenance for decades to come.
Premium Replacement Windows and Doors
Decades-old windows and doors can impact your home’s curb appeal and value, but that’s not all. They could also be raising your monthly energy bills, especially throughout Dorchester’s freezing winters. So work with Capital Construction to make an important change!
- Replacement Windows: Made by names like Marvin, Andersen, and Mezzo, many of our windows meet or exceed ENERGY STAR’s rigorous standards.
- Replacement Doors: Dorchester homeowners love the beauty, security, and energy efficiency of our ProVia doors! We can customize your new entry door, storm door, and more.
Additional Home Remodeling Services
As truly full-service exterior remodelers, no renovation request is beyond our ability to handle.
Masonry
Need repairs for a broken brick walkway? Want a cozy firepit in your backyard? Then call our Dorchester masonry contractors! Utilizing old-fashioned masonry methods combined with some of the most advanced products in the industry, we can repair or build almost anything you can imagine.
Gutters
If you’re replacing your home’s siding or roofing, why stop there? To make the most comprehensive, value-adding upgrade, let Capital Construction replace your gutters, too. With a seamless gutter system (including gutter guards), we’ll make sure that water flows away from your home to prevent costly damage like rot, mold, and mildew.
