"Gary arrived early and examined the house before sending over the roofing team. He then spent the day managing them and ensured that by evening, the job was done. Keep it up!"

"We had a second story deck that was leaking water into the garage. We got 4 companies to come and give us a quote. Two of them were cheaper but they seemed as puzzled as we were about what to do and could not guarantee from future problems. The other company suggested rebuilding the entire deck and was way out of budget. Ryan from Monarch Custom Coatings came with a sample that had several layers to waterproof the deck - we were very impressed that he was very knowledgeable and has a lot of experience with this type of work. He and his crew worked very hard, always professional, prompt, courteous, and our deck looks amazing now. We were so happy with them that we hired them again to redo the garage floors. We have had bad experiences in the past with contractors, so we know that finding a good, reliable, and honest one is very hard and rare. We highly recommend Monarch Custom Coatings!"

"My house was in shambles and required a full makeover. We also wanted to add a shower to the downstairs bathroom for my mom as she gets older and stairs are getting tougher. I got 6 estimates and most came back much higher than the one I received from US Home developers and their definitions of work to be provided was also very vague, and left a lot of room for additional fees. Belle gave me a very detailed contract outlining everything that would be done. Armando was our contractor and like Belle, he was an absolute pleasure to work with. The work was done very quickly and only took as long as it did because of wait times for material. Belle met with us a few times to shop for material and helped us through the design process which was very helpful because I was stressing out on this aspect. Armando made sure everything was the way I wanted it to be and was very flexible when it came to scheduling. At the end of job he even had all the junk in my backyard, which was a lot, picked up. I was so happy with the work they did downstairs that I decided to rehire them to do the upstairs. They even added roof replacement to the contract for an additional price that was much lower than the 4 other estimates I got. My house went from looking like it was straight out of an episode of Hoarders to looking like it’s straight out of a magazine. Couldn’t be happier!"

"From start to finish Will was very professional and knowledgeable about his job. The price he gave me was extremely reasonable and the time allotted for the job was just one day. I checked prices with other company and the cost of work was 3 times over the amount that Will estimated for my house.
Work Day: He came early with his team. All of them very hard working people. They all did a magnificent job. Very trusted people. I did not have any problem leaving my house to them. They even took care of my cats.
My house needed more work and Will did it with out charging more money. It was something that needed to be done and he did it.
Thank you for the great experience as a homeowner. Everyday I come to my house I have a happy face and think about all the work that you guys did leveling the house and fixing the foundation. BTW I do not hear any creaking any more. :-)
If anyone need more information about the work done by Will and his team, please let me know. I will be very happy to provide you with more details.
Thanks,

"While we reviewed the project and determined utilizing different services might yield a better end result, Danny was a true professional all the way through. He showed up on time, provided me with his feedback and guided me through some alternate options. In the end and though this particular project was not a good fit, it is thanks to Danny that I will call upon him and Good Fellas again. Thank you!"

"Brigada builders did a spectacular job on the exterior remodel of our home. They were happy to answer any of our questions regarding the project. They came out and gave us an estimate for the job, which was very reasonable. They showed up on time and no matter how very hot it was outside, got the job quickly and professionally. The guys are very skilled and knowledgeable; I was impressed by their attention to detail and quality of work. The house looks beautiful and we couldn't be happier. Very nice and polite people. I would recommend his company to any of my friends. Thank you, Brigda."

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:
Water in your basement, including damp walls or puddles on the floor
Mold spots in your basement
Musty smells or odors
Warped doors or walls
Cracks in walls
Insect issues, such as cockroaches and termites
You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home.
However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
From average costs to expert advice, get all the answers you need to get your job done.
