He then plugged the hole and mounted the tire back on the rim. He then mounted the tire back on the vehicle. I went to the service desk and paid 15 dollars. I was in and out in 45 minutes time.

He got on a ladder and said my siding was done improperly and gave me some options regarding a repair and recommended I replace the siding since there was no flashing installed under the siding. Knowing that I needed to replace the siding anyway I had him quote me which he did with various options. After agreeing to his estimate his brother came over and fixed the leak to get me though until the siding could be done. Before they were able to start we had another storm and I got another leak which they came and fixed the next day. The crew who did the siding were very professional, they came in did the work and never left a mess. The roofing job on this house is poorly done (on my list to replace this fall) and spent time fixing some of the problems as they went allowing me to get by till fall. I did not ask them to do the extra fixes, they just did them and told me later. They had quite an extensive job as the previous siding company did a lousy job.... no flashing on any of the windows.... really. They also redid the gutters installing leaf guards. The previous gutters were in sad shape and were not pitched correctly and I had water in my basement because the gutters were directing water down next to the foundation. Since the new gutters have been installed, no issues in the basement, no leaks in the house. Great job!!!! Yost is more expensive than the other companies that quoted me but the quality and professionalism is outstanding. The house looks great and I would certainly hire them again. After the siding was complete I asked to have them replace a back door that was rotting off it's hinges. Again, they ordered the door and installed it quickly and with no mess. Great job!!!

FAQs for basement leak repair projects in New London, CT
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 $2,500and $5,000 to waterproof, but that price rises significantly for a larger basement.
