Exceptional craftsmanship, thoughtful design, and deep integrity—JJ Palmer of Maryland Home Improvement Company delivers at the highest level. One morning not long ago, during breakfast, we heard a crash from upstairs. This time it wasn’t the cat getting into mischief—it was a large shelf in our closet giving way after thirty-one years of faithful service. To its credit, the old wire system had lasted decades. But what followed was not just a replacement—it was a complete transformation. We’re now standing in a custom-built white oak closet designed and executed by JJ Palmer, and it’s one of the finest examples of residential craftsmanship we’ve ever encountered. Every detail has been carried out with extraordinary care and quiet precision. The workmanship doesn’t shout—but it absolutely sings. You see it in every cut and corner. Trim lines are crisp and flush, hand-scribed to imperfect walls so precisely that they seem to have grown there rather than been added. Shelf edges are finished so carefully that all end grain is hidden, and the face grain flows seamlessly across components. Even the angled shoe shelves—normally utilitarian—are grain-matched and gracefully proportioned, elevating function to quiet elegance. The layout itself reveals a deep understanding of proportion and geometry: verticals and horizontals are aligned across bays with rhythmic consistency; trim widths are uniform; spacing feels intentional and calming. Every inch of the system—from the sloped shoe racks to the deeper bay for long dresses and luggage—feels purposeful, balanced, and beautifully made. Nothing is extraneous. It’s the kind of design that honors both material and use. JJ selected the materials with a discerning eye: knot-free white oak with straight, harmonious grain, installed in ways that bring out its natural beauty rather than compete with it. Even before stain was applied, the woodwork had presence and refinement. Once finished in a light weathered gray, the result was timeless, tactile, and visually integrated with the rest of the space—including our flooring and lighting.. What truly sets JJ apart, though, is not just his technical ability: it’s his ethos. We’ve worked with him before, on projects ranging from a bathroom remodel to a full basement build-out, and each time, he brings the same consistency of quality, professionalism, and quiet pride in his work. He listens well, offers thoughtful solutions, and always delivers what he promises—without shortcuts, excuses, or ego. In a world where true craftsmanship often feels like a relic, JJ Palmer is the real thing. We recommend Maryland Home Improvement Company without hesitation, and with deep appreciation.

I recently had an emergency electrical issue at my home, and I can't recommend JJ Palmer Electrical Service highly enough. The power was flickering throughout the house, my thermostat was fried, and I had no heat—a truly stressful situation. JJ responded incredibly quickly, arriving with a friendly demeanor and a professional approach. He worked diligently for nearly three hours to diagnose the problem, ultimately discovering that the issue stemmed from the power supply coming from the pole. Without any prompting, JJ took the initiative to call BGE and clearly explained the problem to them in a way I never could have. Amazingly, BGE arrived while JJ was still on-site, and he collaborated seamlessly with their technician until the issue was fully resolved. On top of that, JJ also replaced my damaged thermostat, ensuring everything was back in working order before he left. The best part? His pricing was extremely reasonable for the level of expertise, effort, and care he provided. As a new homeowner, finding trustworthy professionals is crucial, and I’m confident I’ve found my go-to electrician. If you're looking for someone reliable, skilled, and genuinely invested in solving your electrical problems, I wholeheartedly recommend JJ Palmer Electrical Service!

Overall I'm happy with the work. I received the estimate quickly and the work started within a week. I chose MHIC because it was the lowest cost estimate. The overall finished project is fine, but the quality on the taping/spackling could be a little better, I didn't notice until I started to paint the area that there were divots/issues (and I haven't asked MHIC to fix it.) While the project started quickly, I was frustrated with the how the day-to-day timing worked out...and that there was basically one person doing most of the work and that he didn't always have the supplies needed for the day's work.

Work was done punctually and professionally. However, the price was too high, except for the stair refinishing -- that was done well and priced according to competitive bids.

Provider constructed a Deck at the rear of my home that consisted of Composite (Trex) wood, Electrical light fixtures, Stair Well, and some painting to exterior areas. 

Provider constructed a Wet Bar in the finished part of the basement.  The job consisted of Ceramic Tile floor installation,  electrical, plumbing, cabinet installation including accessories, and Granite Counter tops.  Provider also installed the electrical appliances.

Provider installed six (6) ceiling fans to the interior of the house.  This job consisted of all labor intensive electrical work.

Provider constructed a large wooden Shelf to the interior of the garage area.  The wooden shelf sits above the parked cars and serves as extra storage space.

All work provided by this Contractor is excellent and I would recommend MHIC to anyone needing home improvement and or remodeling services.

I worked with the handyman and we were able to accomplish all the tasks in a remarkable short time--4hours!  this was quite a relief for me as these things had been bothering me for some time. I am quite pleased with the results. The handyman had tools that I did not and greater skills. At the same time, tasks that were more complicated or required following written directions were sometimes a problem. For example, the medicine cabinet required a bit of assembly and the handyman thought the shelves somehow belonged on the sides.

JJ did a great job on our basement renovation.  He and his crew were very professional and easy to work with.  They kept my house clean, stuck to the plan, and stayed within budget.  My wife and I are very satisfied with the work that was done and are enjoying our new basement.

Response from Maryland Home Improvement Co
"We are sorry that you are not completely satisfied with the service that you received but we are also surprised to discover this because the list that you provided us was completed in the time allotted and work that was not on your list was also done. Please note that the person who you refer to as a helper has been doing electrical work under licensed electricians for more than seven years which makes him a journeyman electrician."

Showed up as scheduled and got right to work. Although JJ and his talented assistant had never done this particular installation before they read the instructions and figured it out as they went. They were very respectful of my home, working cleanly and cleaning up any debris that was unavoidable. Cutting holes in the ceiling can be pretty messy but they brought their own tarps and even re-covered areas I had pre-covered. The sun tunnels look great and work amazingly well. The ceiling they repaired also looks good. I am so pleased that I have requested a quote on a kitchen remodel.

JJ installed a shower door for us.  The shower was 1 inch out of plumb so the job was very difficult.
Everything turned out great!
