Dan was extremely easy to work with. He made our families emergency renovation process simple and was always available for questions. His company did fantastic work in a timely manner and Everything fell within budget. I would definitely recommend Dan for all your home remodeling needs.

From the beginning of the porch being knocked down. To the rebuilding of my new enclosed porch. Dan and his workers were amazing people. Very professional and courteous people. Beautiful job from start to finish.

Dan and his team just added on a 12×12 composite deck to a existing deck at my home. It came out amazing and we are so happy with it. Dan and his team were excellent and will be using them in future projects, thank you Dan

Best construction company!!! Very responsible and professional. Always on time, always ready to answer all questions!!! Highly recommend to anyone looking either to build a house, to do extension, build a porch or something else. They do free estimates and do the job quickly.

Dan’s Construction just completed a Trex deck with two sets of stairs for me. I am thrilled with the outcome! Dan was pleasant and efficient in overseeing our deck project, his crew worked tirelessly to complete their work, despite bad weather and the issue of trash on my site…

I came across Dan’s Construction by accident while searching the internet and I’m glad I did. I read the reviews and checked out the company and contacted for an estimate. He was quick and professional and reached out enthusiastic to work…

Dan is super nice and easy to work with. His team worked all day to get our roof replaced which had damage down to the rafters. He is knowledgeable, fair and trustworthy. I highly recommend this company and will definitely hire them for future projects.

We called after seeing a recommendation on Facebook and we are very happy we did. We had them build a covered pergola off our back sliders, and since we live in a log home, we wanted rough hewn lumber. Not only did they order the perfect stuff…

Dan and his team completed a full replace of the deck, staircase and balcony at my home. From the beginning Dan was knowledgeable and responsive to my inquiry including being quick to respond to any changes to material or additional items…


Bump-outs, suites, dormers and second stories
Most of Windsor's housing is postwar suburban stock, and the common additions are a family room off the back, a primary suite, a dormer for usable space upstairs, or a bigger garage. On those houses the structure is predictable enough to talk about cost early. The most common asks in Windsor are a primary suite, a family room off the back, a dormer to make upstairs usable, and a garage that finally fits the cars. All four are routine work for us, and on housing of this era the structure is usually predictable enough that we can talk about cost early rather than after demolition. Whether the extra space becomes a bedroom, a home office or more living space changes the mechanicals more than it changes the shell.

Foundation and structural work
New foundation below the 42-inch frost line, or a frost wall and slab where that suits the use. Where the addition opens into the existing house we carry the load properly with a sized header and a continuous path down to the footing, which is the part that gets skipped and the part an inspector checks. Near the green, the colonial and Federal homes need an addition that suits their age, and if the house is in a historic district the design may need review before a permit.

Matching the roofline and the street
Housing in Windsor runs to colonial and Federal homes near the green and a deep stock of postwar suburban housing, and on a street where the houses share a vocabulary an addition that ignores it stands out for the wrong reason. We match roof pitch and overhang, keep the siding exposure and trim consistent, and size the windows to the originals rather than to the current catalog. Curb appeal is the test: from the street it should not read as an addition at all.

Zoning, setbacks and the building permit
Setbacks, lot coverage and building height come from Windsor's zoning code and they decide the footprint before anything is designed. We check them first, file the permit with the Windsor Building Department in our name, and are licensed in Connecticut as well as Massachusetts.

Finishing it, plus remodeling and everything outside
A shell is the easy half. Whether the new living space works comes down to layout, daylight and mechanicals, so we plan those first, then handle bathroom remodeling inside the addition, updated finishes chosen to match the house, and insulation and windows for real energy efficiency. Most Windsor additions turn into more than an addition, and that is usually the right call: our remodeling services cover roofing, siding, gutters, windows, doors, kitchens, bathrooms, decks and sunrooms, so the whole project runs on one schedule with one point of contact.

Common questions about home additions in Windsor
Will adding a bedroom affect my septic?
If the property is not on town sewer, yes, and it is the first thing to settle. Under the Connecticut Public Health Code an added bedroom has to be reviewed against the septic system by the local health department before it is a building question at all, and the answer can change the design or the cost. Whether your street in Windsor is on town sewer is the first thing we check, before design work starts.
What does an addition cost in Windsor?
On Windsor's housing the structure is usually predictable, so the number is driven by footprint, how far the layout moves, and the level of finish rather than by surprises. We still price it at the house rather than over the phone, because the estimate is free and an itemized number you can trust is worth the visit.
How long does the whole process take?
A spring start gets the shell closed in before the weather turns, which is the sequence you want. Later starts work but carry the shell into the cold. The build itself is the predictable part; design and approvals are where the range comes from, which is why we start those first.

More about home additions in Windsor
Where the space usually is in a Windsor house
Windsor's housing runs to colonial and Federal homes near the green and a deep stock of postwar suburban housing. Houses of that era were built to a plan that assumed a smaller kitchen, one bathroom upstairs and a garage for one car, which is why the same four additions come up again and again here.
The good news is that the structure is predictable, so the conversation moves quickly to what you actually want: a primary suite, a family room off the back, a dormer that makes the upstairs usable, or a garage that fits the vehicles you own now.
Windsor is Connecticut's oldest English settlement, and its oldest houses have often been added to more than once. On those we look at the structure first; on the postwar houses the question is usually how much of the layout should change.
Adding on in Windsor
Windsor sits where the Farmington River meets the Connecticut, north of Hartford, with its historic center near the rivers and suburban neighborhoods spreading west toward Bloomfield.
On the low ground where the Farmington meets the Connecticut, flood maps matter. If a lot is in a mapped floodplain, the floor height and footprint of an addition have to account for it.
Most of Windsor's postwar neighborhoods have regular lots and capes, ranches and splits that take an addition well. A second story on a ranch is a common way to double the space without using more of the yard.
How the season shapes the build
An addition in Windsor has one deadline the calendar sets for us: get the shell closed in and weathertight before the cold. That makes the start date matter more than it does on most jobs, because a foundation poured in May and a foundation poured in September lead to very different winters.
Interior finish carries the cold months and is the right work for them. We would rather give you a date that holds than the earliest one we can say out loud.
Zoning and permits in Windsor
Work in Windsor is permitted by the Windsor Building Department under the Connecticut State Building Code, and we file in our name so the code responsibility sits with us rather than with you. We are licensed in Connecticut as well as Massachusetts, and inspections are ours to schedule and meet.
An addition runs two approvals in parallel, and the zoning one is the slower half. Setbacks, lot coverage and height come from Windsor's zoning code, and where the design cannot meet them the route is a hearing for a special permit or a variance. We establish which case you are in before design work starts, because it changes both the drawing and the timeline.
If the house sits inside a local historic district, that review can govern windows, siding and anything that changes a street elevation. We check whether one applies at the start, prepare the submission where it does, and build to what gets approved.
