3-Season & 4-Season Rooms

Whether you’re dreaming of a light-filled 3-season room for summer evenings or a cozy 4-season room that’s livable year-round, Formerly DelPrete Home Improvements has you covered. Our expert team will guide you through every step—from design to construction—to ensure your new sunroom is built to last.

What’s the Difference Between a 3-Season and 4-Season Room?

3-Season Room

  • Designed for spring, summer, and fall use
  • Not insulated or heated
  • Lets in tons of natural light with large windows or screened in openings
  • Flooring is usually decking over screen, though not always
  • Protects from bugs, rain, and wind while staying open to fresh air
  • Cost-effective way to add living space

 

4-Season Room

  • Designed for year-round comfort and is fully insulated
  • Energy-efficient windows and doors
  • Typically heated and cooled with a mini-split system
  • Flooring is usually finished with vinyl plank or carpet
  • Perfect for a family room, office, dining space, or lounge
  • Adds significant value to your property

 

Whether you want a breezy 3-Season Room for summer evenings or a 4-Season Room for year-round living, we’ve got the expertise to bring your vision to life.

Benefits of Adding a Sunroom to Your Home

  • Expand your living space without a full addition
  • Increase natural light and outdoor views
  • Create a versatile space for dining, relaxing, entertaining, or working
  • Boost your home’s curb appeal and resale value
  • Enjoy the outdoors without worrying about bugs or bad weather

Custom 3-Season Rooms

Our 3-Season Rooms are stick frame built with durable, high-quality materials that maximize comfort and style from spring through fall. They’re designed to let you feel connected to the outdoors while staying protected from pests and the elements. A perfect upgrade for decks, patios, or open spaces that aren’t used to their full potential. And depending on your budget, we’ve even built rooms and left the interior unfinished for the homeowner to complete.

Custom 4-Season Rooms

For homeowners who want a true all-season living space, our 4-Season Rooms are stick frame built and fully insulated. They are built to function like a natural extension of your home. With energy-efficient windows, doors, and climate control options, your new sunroom will be comfortable in every season—whether it’s a snowy Massachusetts winter or a hot summer day.

    I recently had my roof replaced by Del Prete Home Improvements (formerly Beantown Home Improvements, Inc), and honestly it was a really smooth experience.The pricing was fair and easy to understand, and the crew was great to work with. … More They showed up on time, worked hard, and got everything done faster than I expected.They kept me updated along the way and were easy to get in touch with if I had any questions. Cleanup was solid too—no mess left behind, which I definitely appreciated.Overall, I’m really happy with how everything turned out. The new roof looks great and I’d definitely recommend them to anyone needing roofing work done.

    Five star experience all round!The communication from the sales and project management teams was first class throughout including the job scope, advanced prep requirements and on-site ETAs.Pre and post job inspections allowed as much time … More as necessary to provide clarity on the existing structural conditions and explain the various aspects of the completed work.The roofing crew arrived on time, were very courteous and presentable, were mindful of the flora, did a great job with the install and clean-up and completed the job in a day as promised.Everything above also applied to Part two of this project which was to replace all of the exterior cedar shingles and wood plank with Hardie fiber cement and trim with a couple of new windows also installed in the garage.Like Derek beforehand Project Managers Jimmy and Dave were exemplary throughout along with Estuardo leading an equally hardworking, courteous, presentable and conscientious crew.Once again this project was completed on time with exceptional communicationthroughout from Jimmy and Dave.There were some minor post-job aesthetics that were identified by both parties (which was very reassuring) but again nothing was too much trouble for them and Estuardo to diligently attend to in a concerted effort to ensure that we, as the homeowners, were left totally happy with the end result.
