Roberts Construction Company custom home build in eastern Connecticut

Building & construction · Eastern CT · RI · MA

Foundation up. One contract. The same crew you talked to on the site walk.

Custom homes, additions, framing, garages, decks, and siding. We hold the contract, we're on site, we coordinate the trades. No handoff to a builder who's never been to the lot.

What we're known for

Single-contract builds, eastern CT geography.

Roberts Construction has been building in eastern Connecticut for over two decades. The work is residential and light commercial — custom homes, family-scale additions, garages and outbuildings, the deck off the back, the new siding when the old one's done.

What differentiates the work is the geography we know. Granite ledge in Sterling. Glacial till and seasonal wet in Plainfield bottomland. Mill-era foundations in Willimantic and Putnam. NPU coordination in Norwich. We don't learn the lot during the build — we already know what it's going to do.

And we hold the contract. From foundation excavation through the certificate of occupancy, you have one number to call and one crew to point at. That's the point.

What we build

Six things we do, all under one contract, with the same crew on the site.

Roberts Construction Company custom homes in eastern Connecticut

Custom Homes

Foundation-up new construction on rural and suburban lots across eastern Connecticut and western Rhode Island. We hold the contract from site walk to certificate of occupancy and coordinate every trade.

  • Programming and design coordination with the architect of your choosing
  • Site-prep, foundation, and framing held under one contract
  • Energy-code-compliant envelope (CT 2024 and IRC 2024)
  • Permit pull and town inspections coordinated on our end
Roberts Construction Company additions & expansions in eastern Connecticut

Additions & Expansions

Second-story adds, family-room and kitchen expansions, garage-with-bonus-room builds. The hardest part is matching the existing structure — foundation depth, framing dimensions, roof tie-in. Experience matters here.

  • Structural assessment of existing foundation and framing
  • Foundation extensions matched to existing footing depth
  • Roof tie-ins that don't leak (the part most additions get wrong)
  • Town zoning and historic-district review when applicable
Roberts Construction Company garages & outbuildings in eastern Connecticut

Garages & Outbuildings

Attached and detached garages, machine sheds, workshops. Sized and sited for how you actually use it — not just code-minimum. Most of our garage builds include a bonus-room loft or workshop bay.

  • Slab-on-grade or full foundation depending on use and frost depth
  • Detached or attached with breezeway
  • Workshop bay, bonus-room loft, lift-rated for car restoration
  • Electrical, HVAC, and door coordinated through one contract
Roberts Construction Company framing in eastern Connecticut

Framing

Conventional stick-frame and engineered-lumber framing for residential and small commercial. Square, plumb, and on schedule — framing sets the tone for everything that follows.

  • Floor, wall, and roof framing per CT 2024 code
  • Engineered lumber (LVL, I-joists, glulam) where the design calls for it
  • Wall sheathing and tape-and-flash air sealing
  • Coordinated with the truss supplier on engineered roofs
Roberts Construction Company decks & porches in eastern Connecticut

Decks & Porches

Pressure-treated, cedar, composite, and PT-frame-with-composite-decking. Sized to the back of the house, set off the foundation properly, and built to outlast the next deck.

  • Frost-depth piers under every deck post (44+ inches in eastern CT)
  • Composite, cedar, or pressure-treated decking
  • Code-compliant railings, stairs, and lighting
  • Coordinated with patio excavation and yard regrading
Roberts Construction Company siding & exterior in eastern Connecticut

Siding & Exterior

Replacement and new-build siding in vinyl, fiber cement (HardiePlank), cedar shingle, and clapboard. Done with the trim and water-management details that the box-stores skip.

  • Vinyl, fiber cement, cedar, or composite
  • Tyvek or Henry house wrap, properly lapped and taped
  • Window flashing per AAMA detail, not 'sealant and pray'
  • Soffit, fascia, and trim coordinated as one envelope

How a build actually runs

Single contract, foundation up, eight or ten or twelve months later.

  1. 1

    Site walk and programming

    We walk the lot together. Where's the house going. What does the slope do. What does the soil report say. We talk about how you'll use the building, what matters and what doesn't. From there we put a real budget together — not a number off a per-sq-ft chart.

  2. 2

    Permits and design coordination

    If you have an architect, we coordinate with them. If you don't, we can recommend one. Design moves to permit-ready drawings; we pull the building permit, the wetlands permit if the lot needs one, and the NDDH septic permit on private-septic lots. That stage takes 8–16 weeks depending on town pace and design complexity.

  3. 3

    Site prep and foundation

    Once the permits clear, we clear the lot, run the access drive, dig the foundation, pour footings and walls. This is our excavation crew on our own machines — no subcontracted excavation, no handoff delays. Three to six weeks depending on size and weather.

  4. 4

    Frame, dry in, mechanicals

    Framing goes up, roof goes on, the structure gets weatherproofed. Then electrical, plumbing, HVAC rough-ins coordinated by us. Building inspector signs off on rough at each stage. This is the longest part — typically 12–20 weeks.

  5. 5

    Finish and certificate

    Insulation, drywall, trim, paint, flooring, cabinets, fixtures. Final inspections. Septic and well sign-offs from the health district. Certificate of occupancy. Walk-through. Punch list. Closeout. We're still your number for a year after the CO.

Frequently asked

What we get asked before a build starts.

Do you do full builds from foundation up?
Yes — that's the core of what we do on the building side. We site-prep, excavate the foundation, pour and form, frame the structure, dry it in, and coordinate the trades through finish. On a typical 2,400 sq ft custom home in eastern CT, the foundation-to-CO timeline runs 7–11 months depending on weather, permit pace, and material lead times. We hold the contract; the trades work to our schedule.
Can you handle the excavation and the build on the same job?
Yes — and that's usually the cleanest way to run it. Single contract, single coordination, no handoff between excavation contractor and builder. Our crews stage themselves: the excavation team finishes the foundation cut on a Friday, the framing crew is on site Monday. Most of our custom homes run this way.
Are you licensed to build in Connecticut?
Yes. Roberts Construction holds a New Home Construction Contractor license through the Connecticut Department of Consumer Protection (NHC.0014110). We carry general liability and workers' comp on every job. Licensing in Rhode Island and Massachusetts is handled per-project where the home is sited.
What's a realistic price-per-square-foot for a custom build in eastern CT?
It depends heavily on finish level and site difficulty, but $275–$425 per sq ft is the workable band for a quality custom build in 2026 dollars. Ledge, septic, well, long driveway, and high-end finish push the upper end. We give a real number after a site walk and a programming meeting — not a quote-day guess.
Do you do additions and renovations or only new builds?
Both. Additions are a significant share of our building work — second-story adds, back-of-house family rooms, garage-with-bonus-room expansions. The challenge with additions is matching the existing structure (foundation depth, framing dimensions, exterior detail), and that's where the field experience shows. Pure interior renovations we generally pass on; we lead with structure, foundation, and exterior shell.
Can you build an equine or agricultural barn?
Yes — we have a dedicated equine services line (see /services/equine) covering barns, stables, run-in sheds, indoor arenas, and pasture infrastructure. Same crew, same trucks, different design code. Agricultural outbuildings (machine sheds, hay storage, milking parlors) run on the same playbook.
