I have a problem with rats getting into the crawl space area. I need a solution to fix the problem to stop them from getting in. I had already hired an exterminator to get rid of the rats already there, I need a full solution at this point.

Hello, We purchased our house last year (Nov) and the previous owners had built an extension of the basement with a concrete patio overtop. The room below it is now leaking significant amounts of water and we had attempted to patch the flashing around the patio doors where we thought the water was coming from, but to no avail. If someone could contact me asap to schedule a quote, that would be helpful. Thank you, Raine

Flooded basement
Vicinity of St. David's Street West in Thorold
I have one basement wall that I would like a quote for covering with one of your products. It is an old thick wall that is stable but has a bunch of effleuressence on it, and I would like to make it look better, as well as provide some insulation if possible. I can send a pic and measurements by email if that is easier. Thanks.

Efflorescence on basement floor, damp insulation on walls closest to driveway and garage. Basement is unfinished. House dates to 1920. I'm looking for an estimate for interior waterproofing, possibly next week (week of July 30) if someone is available. Thanks.
Vicinity of Queen St South in Thorold
Iam looking for options to fix my crawl space and diagnose if we have any foundations issues. Also would like to get a quote to lift house and dig out a basement if this is even possible.
Vicinity of Carleton Street South in Thorold
We recently purchased our home this past december and have survived a winter of water seeping through one corner of our basement floor. We are looking to get quotes for 2 things: 1) looking for an estimate to install battery backup on our sump pump and 2) an estimate/options for the best way to eliminate the water seepage in our basement. It is a finished basement, and we were told that the previous owners had had some waterproofing completed along with a weeping tile system into the sump pump.

Foundation is bowing . I need advise as to what can be done. Thanks
Vicinity of Swayze Court in Thorold
I live in a semi and the entire front wall seams to be leaking or has leaked in the past between the foundation and the structure of the house. I have removed all the interior drywall and insulation and found a 4' section of really wet wood. The rest of the wood was discolored but not wet.

Hello, I'm planning to buy a house in Thorold. While doing the pre-purchase home inspection yesterday, the inspector advised me to get a structure specialist to have an inspection and suggest any repairs to be done. Just wondering can I schedule an inspection appointment. Thank you.

Leaky basement from ground water and a broken sanitary sewer pipe.
Vicinity of Welland St South in Thorold
We just purchased a Victorian home (built 1884). The previous owner allowed one of the basement support beams to be cut for duct work. As a result, there is floor weakness in the floor above. We would be interested in seeing if extra support posts may help fix our situation. Thank you
