D-Core Construction

Home Addition Contractors in Wethersfield, CT

D-Core Construction builds home additions in Wethersfield, CT, next door to our base in Newington. From the historic streets of Old Wethersfield to the neighborhoods off the Silas Deane Highway, we plan room additions and second-story additions that respect the house and the street they belong to.

The houses in Wethersfield range from colonial-era homes to mid-century builds, and each one calls for a different approach. An older house may need its sills, joists, or foundation checked before anything new connects to it. A newer one may have simpler framing but tighter lot lines. We look at both the structure and the lot before suggesting where the addition should go.

Our process covers the foundation, the framing, the roof connection, windows, insulation, and the interior. Electrical and plumbing are coordinated within the project so the new space is wired and plumbed as part of the build. Throughout, we keep you informed about what is happening that week and what decisions are coming up next, so nothing catches you off guard.

D-Core Construction LLC holds Connecticut HIC.0666861 and is licensed and insured. Owner Felipe Perri has 15+ years of experience, and the company's Google rating stands at 5.0. Our office is in Newington, which shares a border with Wethersfield, so the town is part of our regular working area. For homeowners comparing home addition companies, that closeness means site visits, walkthroughs, and questions after the job are simple to arrange.

Adding On in Old Wethersfield

Wethersfield was settled in 1634, and its motto calls it the most ancient town in Connecticut. Old Wethersfield is the largest historic district in the state; it became a local historic district in 1962 and was listed on the National Register in 1970, and the town counts more than 150 buildings there that date before 1850.

Within the district, the Historic District Commission reviews new construction, additions, and changes such as windows, siding, and decks, and a Certificate of Appropriateness is valid for one year. The town encourages homeowners to talk with the district coordinator before filing, and we recommend the same, so the design starts on the right foot.

Questions About Home Additions in Wethersfield, CT

What does the Wethersfield Historic District Commission review?

Its main job is reviewing new construction, additions, modifications, and demolitions in the district. Windows, doors, siding, decks, garages, fences, and outbuildings also need a Certificate of Appropriateness. A certificate is valid for one year once issued.

Should I talk to the town before hiring a contractor?

For a house in Old Wethersfield, a conversation with the district coordinator early on is a good idea, and the town encourages it. We are happy to work from what you learn and shape the design around it.

What if the existing house has structural problems?

We would rather find them before the addition is designed than after. If the sills, joists, or foundation need work where the addition connects, we include that in the scope so you can make decisions with the full picture.

How is the price of an addition decided?

It comes down to size, structure, the roof connection, and the finishes you choose. We give you a written scope that spells out each part, and we talk through options that can keep the cost in line with your budget.
