"Steve is a good listener and followed through with our agreed on plan. His workmanship is one of a craftsman: precise and elegant. Our project involved building on an old foundation which needed repair work and strengthening, which he did, before proceeding. The end result was just what we had hoped for. We are very glad that Steve and his son Adam took on this project which met all our expectations."

"I have used JM for a number of projects from Roofing to Concrete floor in garage. I learned long ago that you get what you pay for. JM might not be the cheapest contractor but the quality of the work is second to none. They put a new staircase outside the front of my home that has 12 steps with railings and I will get many years out of that it is so sturdy and looks fantastic. My home is very old and can be hard to work on but it didn't matter what I asked them to do, they found a way. I will pay a premium for work done at this level."

"contacted T&K Builders after discovering mold in my exterior wall, and their response was immediate and professional. The team quickly demolished the affected area and installed the necessary structural supports to safely hold the roof. Everyone on site worked efficiently, communicated clearly, and maintained a high level of professionalism throughout the process. They kept the site clean, protected materials from the elements, and were extremely organized—especially important since we received over four inches of snow the following day. From start to finish, the experience was seamless and stress-free. Their attention to detail, workmanship, and respect for the property truly set them apart. I would absolutely recommend T&K Builders for any future projects and would not hesitate to call them again."

"Jhonathan and his assistant Juan showed up on time and got right to work. I am pleased with the tree trimming done and the broken, hanging branches that were removed. They took extra care not to drop heavy branches that could damage my deck or fence. I feel I was charged a fair price and will have them back to do some additional work when needed."

"Watry Homes started the job on time and finished quickly.  The project was difficult due to the height of the building and the steepness of the roof.  Crew was friendly and very customer oriented.  The yard and property were cleaned up perfectly.  I have been a contractor for over 30 years and am very particular.  I would recommend Watry Homes highly.

"We had the springs replaced 1st, and the service we received made it an easy call to have them back to do our new GDO. The guys were honest, they came early on both occasions, which was a blessing, and walked me through everything they did, and why they did it. From the secretary, to the gentleman (I’m bad with names, but think it was Brad) who set the appointment, to the service rockstars, I would highly recommend JD Griffiths to anyone/everyone who asks my opinion on a great crew to work on their home."

"The smoothest construction work I’ve ever had done! I LOVE my new kitchen! They were professional, timely, and very fairly priced. They listened to my input, and provided options to me that I wasn’t even aware existed. I ended up with better quality and design for the same price. The “Dan’s” were extremely knowledgeable, friendly and helpful, I cannot say enough good things. If we hit a roadblock, they had solutions ready and waiting for my approval. Most importantly, they were in control of everything. They listened to me, then handled it all, and gave me everything I wanted and more. It was really a dream makeover which I cannot say is the norm for most! I would definitely recommend and will hire them again for all my future projects!"

"Work is basically ok but terrible communication and rather messy, including coming home to find the work crew having taken over my garage as work space without letting me know and leaving a mess for me to clean up. Owner didn’t seem to care and was not communicative of additional costs incurred. I would not recommend."

FAQs for addition to existing structure building service projects in Butler, WI

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.
