"The project went very well and Above and Beyond Construction was very easy to work with. We were very pleased with the quality of the work done. We were given good choices and suggestions in terms of windows, railings, flooring, bathroom fixtures and all other materials used. They were very responsive if we had questions and were flexible if we wanted to make changes while construction was going on. Our home is an older brick Spanish revival home and the owner of ABC went out of his way to find architectural materials for the addition that matched the style of our home. The crew was courteous, conscientious, pleasant, professional and very easy to have in our home. They were very neat and cleaned up every day before going home. We highly recommend Above and Beyond Construction and would use them again on any other projects in our home."

"We are very pleased with the work done by Paul and his team. They were courteous, professional, punctual and easy to communicate with. It was a tricky job becaus of space restrictions and we are happy with the end result and the work was completed within the time frame initally given. We have done some major renovations previously and know that there are so many things that can go wrong in a big job like this but all was smooth and calm. I would definitely use for future jobs and recommend to others."

"It was great to work with Icon Builders to building our dream home. They went out of their way to accommodate the completion of our home build in time for school. Their response times are great and the staff is truly personable. It was great working with Jenna, Natalia, Joe, Scott, Shawna and Charlie. I will recommend Icon to anyone looking to build a custom home."

"Jack took detailed notes during home quote visit and provided us an initial estimate over the phone. His proposal was comparable to other bids we got. We decided to move forward and he sent us a written estimate via email. The first estimate was slightly over original amount due to known possibility with electrical and additional work we wanted. They started the project and it took about 6 weeks to complete. There were some bumps in the beginning with days/time they were working but we were able to sort that out and all was good. Ralph was the main guy that did most of the work. He did a nice job and made sure to clean up after the end of each day. Basement turned out great and We are very happy with it."

"Angelo did everything as planned. We walked over the construction plans before construction started. Site drawing detailed how the finished room addition and sun porch would look after the job was completed. Wife and I were completely satisfied with the finished job. Ready for summer 2021 with or without COVID... Construction crew (Framers) did a fantastic job. Always arrived on time and job was completed on time. Will be happy to recommend AP Builders for any residential construction project."

"They do phenomenal work! I had them finish my basement, and it turned out absolutely outstanding. I had a lot of specific design details and custom touches I wanted incorporated, and they took the time to understand every single one, making sure everything was executed to absolute perfection. Their craftsmanship and attention to detail are second to none. I would definitely hire them again in a heartbeat and give them my highest recommendation to anyone looking for top-tier work!"

They got the job done in the time they quoted and within the budget. Highly recommend them. They did a bathroom and we were so happy with their work we hired them for the kitchen too"

We had two pillars removed and replaced. concrete was laid to keep them level and they painted all of the wood on the front of our house from black to white. Everyone was friendly to work with. I would definitely use them again for future house projects."

"­We are very happy with the new custom home Clean Edge built for us. True to their name, they provide a great attention to detail. The quality of the construction is very high, with solid materials and also an aesthetic on the finishing touches. You have to look very hard to find any imperfections, and then they correct those quickly. The owner is very focused on this approach, providing products and services a cut above the rest. This company is a rare find and I would not hesitate to engage them again any time."

All of them were always affable and attentive to our concerns. RC Brothers Construction has my very strongest and most enthusiastic recommendation.

FAQs for addition to existing structure building service projects in Barrington, IL

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.
