"Dave and his team were great to work with and very professional. Our project was completed within the rough timeline Dave outlined and came in actually UNDER budget. More importantly, Dave and his team paid attention to little details that made the finished product that much better. We felt like we got our questions answered almost immediately and received customized services throughout the project. We completed our project roughly 6 months ago and Dave is still touching up small details for us to get the final product exactly how we envisioned. If you are looking for a hands on, personal, but yet still professional experience, without sacrificing cost or quality, Hashley construction is the way to go."

Jeff Veglia Remodeling was established in 1987 offering full scale remodeling and tile services. This business was built on honesty, integrity, and quality to all clients. Our reputation is based on superior quality at a competitive price and most importantly we listen to our customers. We serve Massachusetts. Please email or call rather than Message Center on Angie's List.

"Well worth the money. Jeff and his crew were responsive and professional every step of the way. I have a small (6' x 6') bathroom. I wanted to rip out the old bathtub and outdated tile and put in a modern walk-in shower. Jeff advised on the layout, I picked out the materials, and a few weeks later it was demo day. The whole process took about 3 months, but part of the delay had to do with the city of Boston's permitting process. I'll be hiring Jeff again the next time I do a renovation project."

We are a Complete Home Remodeling company. We are fully licensed and insured We handle all projects no matter how big or small. We pride ourselves on excellent customer service and quality craftmanship. Call or text us today at (781) 267-1243 We look forward to working with you on your next project.

"The plan was to turn my two car detached garage into living space and then connect it to the main house with a hallway, along with turning the small storage room that it was connecting to, into a half bath. Ryan and Rob were quick on responding the moment I put in the estimate request and they came over the same day just to get an idea if the work could be done. We went over multiple details and they were ready to get started quickly. Work estimate was on par with what others were indicating but with Level Builders I felt like I was being listened to, and working with what I needed versus steering me elsewhere. Project took a little longer than expected since we changed the format a bit and decided to turn that projected half bath into a full bath with washer and dryer hookups. Whenever an issue arose during the construction, I was always informed immediately and asked what I wanted to do. I felt like I had a say in everything all throughout. I would recommend them to anyone that asks because the final product looks amazing! Any issues that came up were fixed quickly and I'm so happy with the results! They are for sure my go to team for any future projects I have and am so grateful for the work they've done. Thank you!!!"

Addition to existing structure building services FAQs

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
