"Just had ours put in, and it looks great. Our installation team ( Lenny, Terrence, and Manny ) were on time, friendly, hard working and meticulous. Lenny took time to explain things when I popped down and was very patient with questions while working incredibly hard. We have friends who literally live in a swamp who had Busy Dog a couple years ago and their system has worked perfectly. They were getting water in their basement several times a year-- now NOTHING. And I love the technology innovations by this company, the quality of the materials is top notch. Salesman Mike worked with us to set up the construction, he and their engineer came out several times to make sure they understood our tricky set up and worked to get the timing right for timing that worked for us"

"We started having water leaks on a basement wall. Started slow but increased. We made the mistake of calling the big name TC H......, waited weeks to schedule first appointment. Finally showed up and proposed major excavation of basement wall, then applying new membrane. Unfortunately in our house, every external connection arrives via that wall. Talking electric, cable, septic, well water, and sprinkler. They wanted to use excavator to dig but wouldn't take responsibility for any potential damage. Price tag was very high. I was very nervous about this of course. I saw one source of water was around well pipe and other was wall itself. Contacted Marquis Well in Sanford who showed up immediately. Proposed hand digging at a lower price. They scheduled quickly, hand dug all the dirt, found Crack in water pipe casing and sealed up. But wall still had issue. Searched further and found Groundworks, lots of positive reviews. Called and they arrived quickly to assess. Beth is a true professional who knows her business extremely well. We signed proposal to inject sealant into cracks from inside of wall. Josh arrived to perform the work. He was effecient, very experienced who knew exactly what to do. During his inspection, he recommended bypassing one of the smaller Crack where water was never seen, thereby reducing our costs....unheard of! He completed the work quickly, zero mess or damage to our house. I cannot recommend both of these companies any higher. Both were outstanding in every aspect. Don't fall for the big ads from the others!"

With over 25 years of experience, Loyd's Home Improvement has designed and build several Handicapped decks and ramps. Call today for details! Additional DBA - Harold Loyd.
"The project was twofold. The sunroom needed three new sliders after damage from frozen pipes. Harold’s men installed the doors but made a mess of the casing on all three. Unevenly matched etc. Harold attempted to fix it. The second project was two remove clapboards on back of house and replace with shingling. He also suggested that the kitchen casement window needed replacing. We paid $1042.00 for the window. He never came back. We waited 6 months and I contacted him. He assured me he would have the window installed. He was a no show. I’ve made several attempts to get him to finish the job. We went through a cold winter and he had left the shingling open around the kitchen window. He also never installed the outside light on the back of the house after removing it for work. I fired him and yet he tells me he doesn’t have the money. I am short of going to small claims court. People beware!"

FAQs for basement leak repair projects in Nashua, NH
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
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.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
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.
