"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!"

Their vision and our visions come together turns out spectacular. We love working with all of the talented employees, they are courteous, kind and always ready to make it right if I change my mind or do not like something.

Since buying our home Amro has done 100% of the work in the past 18 months, they will continue to do all of the remodeling on our home in the future.

"The kitchen turned out better than I could have imagined and was a completely gutted down to the original floorboards.  As part of the remodel a wall was taken out in the kitchen to open it up, the existing pantry was moved to make room for the new refrigerator, and the pantry was relocated to another location in the kitchen.   Old fluorescent track lighting was removed and recessed lighting was added. Additionally we removed the outdated plant window over the sink and replaced it with a new, modern, more insulated window.  Wood floors were added to the kitchen as well as throughout the entire first floor.
 The master bath was also fully gutted and enlarged to allow for a larger shower with frameless doors, new, larger vanity and soaking tub and bathroom window was also replaced.
As any remodeling project goes, unanticipated problems pop up and we certainly had our share with this old house.  AMS was very fair in analyzing how best to resolve the problem at hand and also containing the unanticipated costs.
The kitchen and bath remodel were completed about a month ago and we are now in the process of working on Phase II, updating the hall bathroom / shower and replacing the carpet on the steps with wood steps and an updated banister.  Thanks to AMS, our house is now a place we call home and we thoroughly enjoy spending time in our new kitchen and bathroom

"Very well. Robert explained the work they would do and he coordinated tile, plumbing and countertop replacement. We had an early 80's kitchen that needed help but we didn't want a major renovation. They updated our cabinets with new, larger doors, painted the frames, added soft-close hinges, and constructed a new cabinet to replace a built-in desk. New backsplash, granite countertops, and hardware. Their work was a superb value and we're pleased with our new "bright" kitchen!"

"They did a good job.  He was great.  They did a really spectacular job.  We put on a new addition and it's really tricky to get the garage door.  They had to custom fit it and they made it work great.  I'd give them straight A's.  They had very competitive pricing. "

"We had a great experience with Granite Works. We contracted our countertop work on July 28th. We feel very fortunate to have met Art. He is very professional and not a high pressure sales person.  He was more of a designer and he took us out to the slab yard helping us find slabs that matched our kitchen design and equally important budget.. We were able to use their sample cabinet materials and coordinate them with the slabs, colors, movement and patterns.  He advised us on the best cuts, edgings, care, etc. Once we selected the granite within a few minutes, Art presented us with an estimate on the spot.  We placed a 50% deposit and the next day the office assistance called us to schedule our on site template. The template process was easy and thorough. It is very helpful if you take your kitchen photos with you and your detailed measurements.  That way your estimate is accurate and Art can help you with balancing movement, appropriate area for seams, if any.  Granite works provided the granite, onsite measurements, sink options, bull nose edging and included all cut outs, plus an Angie's List discount. Our price was $2500 less than a company in  the Mt. Airy. Within a week we had a template completed, in two weeks the fabrication of 2 slabs, and the installation of occurred on  August 9th. In 1 day! We elected to forego their 4" backsplash option and we designed and installed our own. Art's design consultation was very helpful.  After we finished 1/2 the backsplash we sent Art a thank you email with a photo.  He was so surprised and we were surprised and happy 1) he remembered us, and 2) he liked our natural stone tile work.  We recommend Granite Works for quality, professionalism and price.  Good luck and thanks Angie's List. Art and Granite Works Rocks!!"

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