What’s the Difference Between Remodeling and a Home Addition?
While remodeling transforms the inside of an existing space, an addition expands your footprint—giving you more room to live, work, and relax. Additions may include:
- Entire rooms (e.g., family room, master suite)
- Secondary structures (e.g., garage, detached ADU)
- Vertical expansions (e.g., second-story additions)
- Functional extensions (e.g., bump-out kitchens or bathrooms)
Remodeling reshapes what you already have. An addition gives you more of what you need.

The Design Phase (Steps 1-5)
Complimentary Consultation
Our project consultant meets with you to thoroughly evaluate your project. We want to completely understand your needs, wants, and vision.
Preliminary Design
We measure, photograph, and document your home’s existing conditions, custom designing a solution specific to your needs.
Intermediate Design
We’ll review your budget and project scope together, and you’ll have the opportunity to approve the preliminary designs before moving forward.
Final Design
With your project consultant and designer by your side, we’ll help you choose finishes, confirm the final design, and walk you through the project details step by step.
Construction Agreement
We wrap up by putting together a complete build-ready package, finalizing the paperwork so you’ll know exactly what to expect when construction begins.
The Build Phase (Steps 6-10)
Orientation Meeting
A production manager is assigned to your project. He will manage the day to day operations of your project, review your schedule, & address any concerns or special requests.
Pre-Construction Meeting
Before we begin your project, a meeting is held to walk-through
the procedures, production schedule, specifications and construction plans. We address any questions or concerns you may have prior to starting.

Production
During this stage our team members will ensure that your project runs smoothly, keeping the job site as clean and organized as possible.
Completion
We will conduct a final walk through to ensure that every detail is complete.
Warranty
Our team stands behind our work with a 5-year unconditional labor warranty and three annual inspections.

WHAT CUSTOMERS SAY

Three years after Capizzi changed out my Velux roof window, I hired the company again to replace all nine of the failing double hung windows in my condo. Every step of the process was made as painless as possible - not easy with a cat in the house. I am beyond pleased with the results and recommend Capizzi Home Improvement highly for anyone planning a renovation of any size. They care and it shows!

Great job opening up the wall between the living room and kitchen. Great people to work with. We have them back to replace our skylights. Thank you to Gary and Diane. The Stone's

From start to finish Capizzi Home Improvement was extremely professional. As a frequent remodeler I was very pleased with the sales, service and production process. I would highly recommend.

Prompt response to all questions; high-quality Mid-Cape roof completed in timely fashion; good value for excellent work.

Love the fact that they keep you informed about when they will be at your house and they are very prompt. All the workers are very pleasant and repect the work place. They were 100% on line wwith what they quoted and time frames,

When we embarked on the journey of basically tearing down our kitchen and laundry room (ceilings and floors included), we knew we needed more ideas and knowledge than our own. The end result were spaces that were taken apart and then re-built meticulously. From the design team, to the project manager, demo, sheetrock, insulation, plumbing, electric, wood floor construction, fine woodworking and painting teams, - we watched our space transform. But more importantly, we realized it was not something we could ever have accomplished alone because each of these teams had the experience, expertise and synchronicity to make it what it is. It is important to say that no project ever goes without a glitch, and even these were handled by the project manager - which just made us glad we had trusted the Capizzi brand and their reputation and relationships. Bottom line is we highly recommend Capizzi Home Improvement and are already saving for our next project!

Not only did they tell us about a 20-year warranty on a 19-year-old bank of six windows, but they honored it. Amazing!! Matt installed them perfectly.

Very informed workers, excellent advice and work, back quickly to resolve few oversights on a large project.

Capizzi converted a garage to a room, installed new roof with trim and gutters. Bill Reis was a excellent project manager, always promptly responsive to any issues. Some small surprises were handled promptly and professionally.

Everyone I dealt with at Capizzi were really great and helpful. The work was done earlier than expected and they did a great job.

Capizzi Home Improvement far exceeded all of our expectations. From Gary, our project mgr, to Dylan, who did all exterior woodwork, and Matt finishing all interior woodwork, our room addition turned out amazing. Professional and friendly, punctual, and clean. They were a pleasure to have working in our home.

Everyone is professional, works hard, and are good listeners. Thanks for helping me get the house I’ve always wanted.

The project manager Bill was prompt in addressing any concerns and making the entire experience a pleasant one . I would recomend Capizzi hidhly to anyone considering home repair or improvement. Sincerely Marguerite Ormon

Tom Capizzi took care of the renovations of my home including custom sized windows. My experience with the Capizzi employees who worked on my hone for several weeks, was they are reliable and honest. They pay attention to detail and, although it may only matter to me, they cleaned up everything after themselves. I wouldn't hesitate to engage them to work on my home again.

My husband and I wanted to add a master bath and walk-in closet to our home and we contacted Aaron at Capizzi Home Improvement. We were extremely impressed with everyone there right from the start! From design to the finished product it was all accomplished in a short 4 month period. Gary and all of the subcontractors were great! They all took pride in their work and it shows! We have an amazing bathroom and walk in closet that has surpassed our expectations! Thank you Capizzi and we look forward to future projects! Sincerely, Keith & Jeanne Cliff

Capizzi Stands by Their Work! A few years ago, we hired Capizzi to renovate our old house and put on a 1,200 sq. ft. addition. They did an excellent job modernizing the old part of the house blending the old and the new seamlessly. Since then we have had a few things that needed to be fixed, some adjustments to the windows and siding. Every time we have called, Capizzi came right out and fixed or adjusted anything we wanted no questions asked. Our past experience with other contractors is once the check is cashed you never see them again but that is not the way it is with Capizzi, they stand by their work. It is very comforting to know that Capizzi will be there for us now and the future. We couldn’t be happier with our choice to use Capizzi for our project. Les Hull Sandwich, MA

Over the past 5 years I have contracted Capizzi Home Improvement for 3 different jobs at my Summer home in Hyannis and was very pleased with the result. Three door replacements, removal of an old deck with construction of a new 16' X 25' deck, and most recently installation of over 20 new windows. All work was professionally handled from start to finish and there has always been a follow-up review yearly to check on the work. Should I need additional work, I would certainly call Capizzi to review the project first.

VERY GOOD! Quality work! Lived to timelines! Good communication! Strong Subs! Saved the Day! I worked with these folks on a kitchen remodel and deck expansion during the Spring 2015 . Project was progressing as planned, when overnight, a pipe burst in the upstairs bath. Their crew was the 1st on site. I was traveling. Before they called me they already had started the clean up and mitigation. Their quick action save the house and the insurance company lots of money. Of course the insurance companies were overwhelmed. Capizzi got innovative on how the repairs would be paid for. This got my house back together much sooner ( in time for summer) than it would have been without this flexibility. I would recommend. Rick

Back in in the summer of 2009 I called Capizzi Home Improvement to repair rotted clapboard and replace the door on the pool house. I was introduced to Jack Strumski and Tony Pola. After that work was finished decided to replace the windows and slider in the house since majority you could not open. I had recently lost both of my parents decided to do some upgrading and remodeling of my house. I have a new house without moving from having the cellar walls and floors painted to updating the bathrooms, kitchen, walls and ceiling painted, hardwood floors refinished, new decks, new shingles on house and siding, new outside doors, new roof, etc. I have been very pleased with Capizzi.
