"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."

"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."

"I ended up with a completely new house worthy of HGTV. I am truly happy with the entire process from the initial bid to the final cleanup. Len and his crew were truly a pleasure to work with. I would definitely hire them again.

After reading Watry Homes reviews on this site, we contacted them in March. I had reached the point where I no longer wanted to maintain the house, and after researching siding options and speaking to other home owners, was seeking a contractor to install what I believed was the best siding solution, Hardy Plank. It was our intention to have the work done before the summer months, to avoid the disruption and scheduling conflicts which inevitably happen in high season.

Scott Watry came out and inspected/measured the house on March 17, presented window options and gave an overview of the process. Within a week we had an estimate and we gave him the commitment assuming the work would begin as soon as materials were received within a few weeks. The project did not get underway, however, until June 4th, the day I was leaving for two weeks of travel. My wife provided daily updates in my absence, and glowing reviews of Scott's workers, specifically, Paul and Rob who came in and installed the windows and doors. I met these guys later and they are true professionals who pay close attention to detail. The siders were also efficient and meticulous in their work, and cleaned up every day. The crew had a few guys, but Roberto, who appeared to be their lead, was very responsive to every question or request, and went out of his way to be accommodating. Splattered paint on a portion of our patio and sill appeared to be their only misstep.

In the end, we have a job that met our expectations in terms of quality, fit and finish. It was the punch list of several small items and requests which was emailed to Scott in mid-June that made the final conclusion of the project a little rocky. It turned out that part of the roof over our den did not receive adequate flashing necessary to prevent a leak that ensued after five days of rain. Scott insisted that it was the result of layers of caulk installed by someone else, inadequately sealing an inside corner of the roof. Dan, who was sent out later to make the repair, said the caulk and sealing had been done by their siders, and was still wet. Scott agreed to place a drywall patch in the interior ceiling where there was water damage, but I spent the better part of a day painting the ceiling, trim and walls to original condition once this was done. This put a damper on an otherwise great experience with Watry.

We totally respect Watry's workers and the diligence they exemplified every day. My feelings about Scott with him not taking ownership of the leak and the damage it caused was unfortunate because it would have been so easy to simply do so without casting blame on others. I also feel it would have been appropriate to personally stop by at the project's conclusion (today), to ensure he had a satisfied customer. As it was, he called and asked me to give a check for final payment to his worker before he left, without asking me if I was completely satisfied. In my view, the size and scope of our project would dictate that he do so. 

However, I would not be hesitant to recommend them as a reference primarily because of his crews.

"We were so happy with Wes and Robert that we immediately hired them again to do a different room. I’ve never before not been sick of contractors before and ready to kick them out- lol. The work was done well. Everything looks great. They went above and beyond to figure out some weird stuff in my house. They are super tidy for contractors and we could not have been happier."

"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!"

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