"It went very well. I called on Saturday and talked with David, it was arranged they would come by on Monday and fix the step between 9-11, they were actually there a few minutes early and finished within 2 hours, including a trip to get materials needed."

"They are WONDERFUL. From start to finish, Zach and his guys were wonderful. We signed the contract in late fall of 2017. They came out this week and were finished in a day in a half. We have a large roof with high peaks, several valleys, and two places it's very steep. They had a huge crew, each doing something different. They worked well together and worked efficiently. I'm not kidding when I say, our yard is cleaner now than when they started and the roof looks WONDERFUL. I cannot tell you how happy Brad and I are. The entire crew was very conscientious and they absolutely pay attention to detail. I was impressed that the foreman showed up before 7:00 am and introduced himself. The second foreman showed up a few minutes later and did the same. All the guys were friendly and professional and they absolutely knew what they were doing. We're doing our windows in 2020, and they will be the first company we will call to come out and take a look. The roof looks wonderful!!!! Thank you. We are so happy."

Wonderful job on both the painting for the development, and the staining of my deck. Probably the best quality painting that we have ever had in our development. From the beginning, the work, work order, estimate process, etc. was handled in a top knotch way. I have had a number of contacts with the company's owner, Colby, and he has shown himself to operate a well run company.He is very businesslike, returns calls promptly, and has people there when he promises.  I also had dealt quite a bit with Josh, who directly supervised the overall process. Josh is very cooperative, understanding, and very helpful. He always came through on his committments, and it made for a very pleasant experience.


The painting crew, led by Arturo, was by far the best group of painters we have used. I got many comments from other homewoners in the development who were very impressed with their work. They are meticulous in what they do, and the final product shows it.

"We hired SAL Construction to build us a garage in Morton.
All I can say is WOW!!! Nice, polite, honest, clean, punctual?My husband found
them on Google and after visiting their website we decided to give them a call.
They did everything they said and did a beautiful job right on budget! I recommended
them to my sister who needed a tile floor installed in her kitchen. Scott did
an amazing job on the tile as well. My sister was so pleased?Her & I both
would recommend SAL to everyone. Job well done!

The rating is bogus as it is required to be able to submit.

FAQs for addition to existing structure building service projects in Cullom, 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.
