"We recently have our basement finished. I was looking for a trusted and reliable contractor for quite a while. I feel very fortunate that finally I found one. The first time I met Syed from Stellar Remodels company, his honest response left me a deep impression. He is approachable and knowledgeable and experienced in project management. He has worked for many years in the construction field. Syed laid out the entire process very simply for us to understand. It was a very straightforward process. The price he offered was reasonable and great. The construction team led by Ainea was incredible responsive and prompt throughout the entire process. They were great getting back to us with answers to all our questions, and flexible with scheduling. The workers were always on time, nice, kind, and respectful of our home. When we had concerns or issues, they quickly resolved them with extreme professionalism and competence. They did an excellent job from many angles. The transformation has exceeded our expectations. Their work is meticulous and thorough. Their ability to get inspections and necessary permits so smoothly made the entire experience stress-free for us. After a couple of months when the job was done, and I couldn’t be happier with the final finished product which took me by surprise. The finishing product was extremely neat and professional with great attention to detail. The transformation exceeded our expectations. It has proved that we have made the right choice and decision to hire this company to get our basement finished. Thank you all for what you have done to make our basement beautiful.

"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 have always put our customers first in delivering what we promise without any gimmicks. The reputation of our company is proven through our satisfactory track record including winning the highly coveted Angie’s List Super Service Award and being selected as a Best Pick Report contractor on numerous occasions. The staff at our company values your time with prompt on site visits, quick turnaround in providing cost estimates, and a responsive attitude until job completion. We can assure you that our pricing and written warranty provides value in your investment when compared with other professionally licensed contractors. Due to our staffing requirements we are only able to take on jobs $10k or higher.
"I am giving All Renovations 5 stars for the basement renovation in large part because of Adrian’s excellent craftsmanship and attention to detail. Our job was pretty extensive. It included moving support columns, demo and rebuild exterior stairway, adding a full bath, extending the finished/framed portion of the basement, moving the circuit-breaker panel, and re-doing our half-bath. The job took 6 months, which was about twice as long as we expected. Omar was always very responsive and provided good feedback. Adrian is very good at explaining things and soliciting your input when options/alternatives exist. He definitely does not take short-cuts if quality would suffer. He is also very considerate/careful inside your home and cleans-up after himself. Our $102k project ballooned to $125k, mostly due to nice to have add-ons and unforeseen issues. But there were several items I feel should have been caught at the contract onset. E.g. the need for a floor drain ($900), considering that we were getting rid of the utility sink basin. There was also an extra $4k to replace the drywall in the half bath since the existing paint was too textured (sponge) to paint over. But we were very pleased with the outcome and would definitely recommend All Renovations."

"Ruben and the team did such a great job on the first project (2-3yrs ago) that I asked them to come back and finish my condo's water heater closet, which showed wear and tear from past water damage. They did a fantastic job in repairing the closet and adjacent living room's dry walls that it looked seamless to the rest of the unit. The team was always conscious of keeping the work area clean as they closed the area off with tarp and placed drop cloths down. I greatly appreciate the amount of high-quality work done in a short time span, especially when asked within two weeks of the project starting. I've recommended the team to my family and friends if they ever need a job done right by a team who is professional, courteous, and knowledgeable."

General contractor servicing Montgomery County and parts of Washington DC. Willis Builders is a family owned and operated company, that specializes in additions, kitchen, bathroom and basement remodeling. Our team is skilled in all aspects of residential construction. Willis Builders has built a business on honesty, dedication and hard work. Our goal is to make your renovation dream come true! Contact us today to schedule a free estimate.
"Willis Builders did 2 full baths & kitchen reno + laminate floor install on main level of our modest 3-story T/H (Jan-Apr ‘24). Marcelo was our PM and as many others say, his crew did not disappoint. Willis was neither the highest nor the lowest quote of several but we felt Matt Willis presented the most honest and realistic estimate for our project and he hit that nail on the head. They might say we bothered them with questions; we might say we had to nudge them a few times. We did our homework to help things move along more smoothly & they did their best to accommodate us. We purchased a bunch of stuff before choosing a contractor. No matter what we threw at them, installation was a success which is a testament to the knowledge and capabilities of Marcelo & crew (Horatio, Frankie & “George”). When we were undecided or unsure about a product, Marcelo steered us toward better or more appropriate alternatives. We had no issue, as a few others suggested, with crews leaving things clean at the end of the day. Our T/H is small with limited space for them to work/store materials & equipment. We never felt compromised during 3 months of disruption. (And we never hesitated to leave our home when work was being done.) Is everything perfect? No, there is no such thing as perfection in an almost 40-yr old house reno or any reno for that matter. There were a few glitches as we expected, but uh-ohs and problems that arose were resolved promptly. We waited to post this glowing review of our project to see if any problems showed up, and none did. Until the ceiling in our bedroom collapsed several months later which had absolutely nothing to do with their work. We are so thankful that we had no reservations about sending Matt Willis an SOS for help with our emergency. In fact, we were so confident in his work that we decided to add painting and a carpet upgrade to what has become an almost total house reno. Again, Matt’s estimates were fair and reasonable, such that our confidence in his company allowed us to forgo spending time getting quotes from others. Matt told us repeatedly how good his ‘drywall guy’ was, and he did not exaggerate! Will & sidekick Carlos were fast and fastidious! The carpet install was equally quick and painless. We are so very happy with the results of our sudden and unexpected 2nd Willis project. We're sorry we didn’t get a chance to rave about how thrilled we are with the results of our 1st until now. If you’re considering home improvements, we highly recommend you consider Willis Builders. We’re doubly happy we did!"

The average cost to hire a handyman ranges from about $40 to $140 per hour. Average project cost ranges between $180 and $700, but the cost per hour and per project depends heavily on the type, size, and complexity of the project. The pro’s experience level and your location also factor into how much a handyman charges per hour or per project. You can also expect to pay higher rates or additional fees for emergency services, or around periods of high customer demand, like holidays.
Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity.
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.
Knowing if you need an architect for your project can be tricky, especially if you've never worked with one before. In general, small remodeling projects like replacing fixtures typically don't require the expertise of an architect. However, larger projects, like moving walls or adding an addition to your home, should include an architect to ensure the project is structurally sound.
The cost to build a detached garage for two cars costs about $26,400 on average. Prices range from $19,200 to $33,600, depending on your location, the garage size, height, materials, and site prep required. Additional cost factors include any plumbing, electrical wiring, and insulation. If you need to build a concrete foundation for a new detached garage, you can expect to pay $1,000 to $8,600 for this essential addition.
