Home additions expand your living space and add value to your home. We design and build room additions, bump-outs, second-story expansions, and sunrooms. Our licensed general contractor manages every aspect: structural design coordination, permits, framing, electrical, plumbing, roofing, and finishing. Your home grows with your needs.

Connecticut home additions require careful planning and code compliance. We coordinate with structural engineers, pull permits, and manage building inspections through completion. We handle foundation work, framing, weatherproofing, and integration with existing homes. Every addition is built to match your home's architectural style and building code requirements.

As your general contractor, we manage the complete addition project. We design the addition layout with you, coordinate with engineers and architects, handle all permits and inspections, and oversee construction from start to finish. One contractor ensures the addition integrates seamlessly with your existing home. Hartford County's housing stock leans heavily on colonials and capes built in the postwar decades, and matching a new addition's roofline and siding reveal to that original construction is what keeps it from looking bolted on.

Every TJ's home addition is quoted on-site with upfront pricing, and you approve the price before we start. Free estimate with no obligation. Addition costs vary by size, finishes, and structural complexity.

Our Process

01
Free Consultation and Design Planning

We discuss your addition goals (extra bedroom, larger kitchen, sunroom), assess your home's structure, and plan the layout. We sketch designs and provide conceptual estimates.

02
Engineering and Permit Coordination

We coordinate with structural engineers for design and safety. We pull all building permits and submit plans to building department for approval. We manage the permit timeline.

03
Construction and Framing

We prepare the site, build foundation if needed, frame the addition structure, and coordinate inspections at each phase. Our crew ensures the addition integrates structurally with your home.

04
Finishing and Final Inspection

We install roofing, electrical, plumbing, insulation, drywall, flooring, and all finishes. Final building inspection approves the completed addition. Your home now includes the new space.

Frequently Asked Questions

How much does a home addition cost?

Home addition cost depends on size, finishes, structural complexity, and whether utilities need extension. We quote on-site with upfront pricing, and you approve the price before we start. Room additions typically cost less than whole-home renovations.

What types of additions do you build?

We build room additions (bedrooms, offices), bump-outs (to expand kitchens or bathrooms), second-story additions, sunrooms, and covered porches. We design the addition to match your home's style and neighborhood context.

Do you handle all permits and engineering?

Yes. We coordinate with structural engineers, pull all building permits, submit plans, and manage inspections. Permit handling is included in our general contractor services. Building officials approve designs before construction starts.

How long does a home addition take?

Timeline depends on size and complexity. Small bump-outs take 6-8 weeks; larger room additions take 3-6 months; second-story additions take 4-8 months. We provide detailed timelines during your consultation.

Can you match my home's architectural style?

Yes. We assess your home's existing architecture, materials, and style. The addition integrates seamlessly with your home's exterior, roof line, and landscaping. We prioritize architectural consistency.

Do you extend electrical, plumbing, and HVAC?

Yes. We extend electrical circuits, plumbing lines, and HVAC distribution to the addition. Our in-house and regular sub crews coordinate these systems for seamless integration with your existing home.

TESTIMONIALS

What Hartford County Homeowners Are Saying

★★★★★

"Highly highly recommend TJs! I used them to help with some debris and junk removal that we had been putting off and they were super professional, incredibly helpful, and non-judgmental. They were affordable and saved us the hassle of renting a dumpster and having to haul stuff ourselves."

Abby Levandoski Connecticut
★★★★★

"The team that came to help clean out our garage and get rid of some big items in the yard was fantastic. The estimate they gave me at the beginning was exactly what I ended up paying. The guys were very fast and got everything out in about 30 minutes."

Liz Turner Connecticut
★★★★★

"I reached out to TJ's because they were independently owned and had excellent reviews. I had become overwhelmed by the garage and basement. In 2 hours the areas were cleared and cleaned. The staff were respectful, professional, and non-judgmental. I highly recommend them."
