Top-of-the-Line Roofing from GAF and More

With Capital Construction’s GAF Master Elite contractors, your roof isn’t just a roof. It’s a Lifetime Roofing System—designed to withstand Dorchester’s tough climate and backed by GAF’s premium warranty coverage. After helping you design your new roof, we’ll make sure it’s installed to provide the durable, weathertight performance you need.

Certified Installers of James Hardie Siding

As with our premium roofing from GAF, we’ve worked hard to earn certification from the best siding manufacturer in the industry. As James Hardie Elite Preferred Contractors, we offer fiber cement siding that is:

  • Built to Resist Fire, Termites, Mold, Mildew, and Rot
  • Durable Against Wind and Hail Damage
  • Customized in Your Choice of Fade-Resistant Finishes
  • Protected by Industry-Leading Product Warranties
  • Installed by Award-Winning, Factory Trained Crews!

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.


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.


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.

Beautiful New Bathrooms in a Day

In addition to our suite of exterior remodeling services, we’re a proud installer of Bath Makeover bathing features. That means that we can totally refresh your bathroom in as little as one day! By custom-fitting a new feature that’s made for your specific space, our Dorchester bathroom remodelers will save you time and money.

Our many bathroom remodel options include:

  • Replacement Tubs
  • Replacement Showers
  • Accessibility Solutions
  • Wall Surrounds
  • Accessories
  •  ... and more!
