"I recently had Advance Guard build a new deck and replace my old wrap-around porch, and the results are outstanding. From the start, Dave was professional, knowledgeable, and passionate about his work. He listened to my ideas, offered valuable suggestions, and kept me informed throughout the process. The craftsmanship was top-notch, with great attention to detail. The new deck is spacious and beautifully designed, using high-quality materials. The porch replacement blends seamlessly with the new deck. The job site was always clean, and the project was completed on time and within budget. Dave was approachable, communicative, and dedicated to customer satisfaction, making the entire experience enjoyable. I highly recommend Advance Guard for any home improvement projects. The new deck and porch have transformed my outdoor space into a stunning area I'm proud to show off."

Located in Everett, Massachusetts, our company travels throughout Boston and New England areas to bring builders and home owners dreams to life. We are committed to excellence and will work endlessly to prove to our clients that they made the right choice with Iwano and Sons Construction, Inc.

"Keep looking! Do not use! I hired Iwano and Sons for a high-spec paint job on my house. Scraping, power washing, priming, caulking, carpentry and repairs as needed, and 2 coats of California paint. The job was done, but in less than 3 years I had significant pealing and cracking on 3 sides of the house. 3 years is past the 2-year guarantee, but the level of failure experienced in such a short time should have been addressed. I brought it to Gabriels attention and offered to supply the paint and to address the first story issues myself. I just wanted the parts that required 2nd story work to be done with his labor. He agreed, BUT ONLY IF I PAID. I moved on from this supplier. In addition to this, when originally doing the job he did not address an area where rotting wood should have been replaced. Neglecting the repair at that time resulted in much more advanced damage and required more rework and with it more cost when it was addressed. I'll mention also that the carpentry was on a time and material basis and would not have cost him profit from the paint job. Doing the work would have been more revenue for him. Do not use this supplier. He does not do the work correctly and if it does fail, he does not stand behind his work."

FAQs for addition to existing structure building service projects in Boston, MA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
