"I’ve used Allen and his team on multiple projects. He is my go-to contractor because I can trust him to tell me what I need and what I don’t need to have done in a project. His prices may be higher than others but the quality is worth it. In this most recent project, Allen took my laundry area from concrete and concrete block, to a fully finished laundry room complete with new appliances, counters and cabinets for storage and folding, a space for drying clothes to hang, and a closed off utility space. Additionally, he changed a half-bath to a full bathroom with 5-ft shower. To do this, Allen, Jeff, and Ryan had to dig up the concrete floor to move pipes; had to replace copper piping, and reroute ductwork. In doing so, they found that my dryer had been venting into my ceiling rather than outside, which was a fire hazard. I am fortunate that they found this. As the project was wrapping up, I had them paint and add new flooring in the family room adjacent to the laundry and bathrooms. I also had them replace my backyard fencing, relocate the outside spigot and hose attachment. As with all of my projects, Allen’s the attention to detail was beyond compare. He kept me in the loop when problems or decisions need to be made."

"We had Top Remodeling handle our home addition, and they did an excellent job. From the initial consultation to the final touches, their attention to detail was impressive. The additional space seamlessly blends with our existing home and has added tremendous value."

"A year ago, I hired VKB Kitchen & bath to build an additional master bathroom and renovated old bath. The great president, Paul P Ibrahimov assigned me a wonderful project manager, Will Vusal for my project. I am grateful to have Mr. Will to be my project manager. He and his team did an extremely marvelous job for the additional master bath and old bath remodel They look beautiful and credential. I have given 5 plus stars review for their job through google review. Today I want to recognize MR. Will, the project manager for his continuous responsible of customer care service and help to resolve any problems they have. He is doing his best to uphold the vkb company core values by guaranteeing a two-year warranty of the quality. Exp, my 88 years old mom was waiting for help with the removal of the shower drain filter to clean it. When I called Mr. Will for the help, he came by himself today to help to resolve the problem. My mom is happy she will be able to use her shower ag"

"From the start to finish, we were very pleased. When Custom Home Creations Partner Garrett arrived, we were impressed with his thorough assessment of what work was needed and what we wanted done. His proposal was right on point with what we expected. The construction team arrived on time, were professional and they efficiently completed the project within the time frame we were quoted. We now have a beautiful, safe and secure pressure-treated wood deck and stairs and we look forward to staining it in early Spring. Here's our "Before and After" photos! We would definitely hire and recommend Custom Home Creations for future projects!"

"Basement Project We absolutely love our new basement! I was very nervous when selecting the contractor for this job. I interviewed three contractors for the job, all seem very decent, but what set Best Home apart was Jeff Segovia. He designed the whole layout of our basement (we love it) and oversaw the entire project from beginning to end. The construction crews were very polite and friendly. Best Home did an excellent job and very flexible with many changes I had and they completed the job on time (took 3 months and exactly 1 week)which was amazing. I am actually hiring them again for additional projects. I highly recommend Best Homes!"

"We had wanted a screened in porch for a while and began to talk with contractors in Spring 2019. We felt very comfortable after talking with Goliath that not only were they capable and in the ballpark of the other estimates, but that they were truly committed to quality work. We began working with them on the designs and specifications, and we had lots of questions because although we knew generally what we wanted, there were lots of details and decisions to be made. They struck the perfect balance of making suggestions, pricing out options, and providing guidance without dictating changes. We changed our minds several times about this or that and they were always amenable. I should note that the job was not only the addition but replacing two large windows in the back, one with a custom sliding door and the other with 3 windows. The addition included a deck, an outdoor gas fireplace and TV, so they had to run electric and gas line. They also replaced our roof and gutters. There were challenges (the shop we bought the windows from dropped them loading for delivery, the inspections were, at times, nightmarish), but Goliath stayed calm, made adjustments, and pushed through. I should also say there were many crews working and all were extremely professional and respectful. We would definitely use Goliath again and would highly recommend them to others."

"We used PI Kitchen and Bath in Frederick to completely remodel our master bathroom. We wanted to update the entire space and make it feel more comfortable and modern, and the finished bathroom is exactly what we were hoping for. There was an unexpected issue during the project that required some additional attention. Our project manager was very responsive and handled it right away. For us, that was actually one of the things that stood out about the company. Remodeling can have surprises, so seeing how a company responds when something doesn?t go exactly as planned is important. They made sure it was corrected properly and kept us informed. The tile work and overall finishing look beautiful, and we?re very happy with the quality of the completed bathroom."

"This was a great experience all around.  We looked at Talon and another construction company.  The other company had a hard time "getting it", i.e., what we were looking for, but when we dealt with Talon's designer and partner, they did.
We did get both bids as close as possible in terms of what was being offered.  Talon's pricing was competitive.
The project was contracted for in August 2013, and completed April 2014.  There was some initial delay waiting for utility companies to move the meters -- some of this was facilitated by Talon and some I had to work directly with the utility company.  This was the most frustrating part of the experience, but I think most of the delays were from the utilities themselves.  Washington Gas was particularly hard to work with.
Demo of our portico was finally initiated (start of construction) in November.  The construction crew worked through some tough weather as the winter of 2013-2014 was pretty fierce.  Loss of time due to weather was minimal, though, as unless there was a huge snowfall, they were out there.  The carpenters who were here on a daily basis were competent and friendly.
We couldn't be happier with the final product, and often neighbors come by or stop us on the street to compliment us on it.

FAQs for addition to existing structure building service projects in Monrovia, MD

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.
