Work Requests From St. John's, NL
Pennywell Road in St. John's
I need 7 jack posts installed in my crawlspace, and possibly the lamination of 2 beams.
Brazil Street in St. John's
I get water in my basement when there is a lot of rain. I live in a rowhouse in the downtown area of St. John's. The basement was redone 2 years ago when I bought the house. There is no drain, but the water only gets up to 2-3 inches and seems to run out somewhere. Would love to know if a sup-pump could be installed or if there was a way to stop to water altogether.
Reid Street in St. John's
Good day! I would like to renovate crawl space in my house: install a good drain system and a sump pump; encapsulate; install dehumidifier.
Empire Ave in St. John's
We have a 1200 sq. Foot home that needs vapour barrier put down in the crawl space and spray foam insulation in the crawl space as well to keep the floors warmer and musty smell out.. Would appreciate a quote! Thanks!
Prowse Ave Ext in St. John's
Getting water in my basement after heavy rain and with spring snow melt. I would like an opinion on a sump pump or other water sealing methods. Thanks
Hamilton Ave in St. John's
Hello! Recently purchased and moved into a house in downtown St. John's. We have had some issues with the water table rising in the crawl space, and we are under the impression we require a sump-pump to be installed to address this. Additionally, the insulation in the crawl is subpar at best. Just batt insulation in the ceiling/floor. We are constantly losing heat through the floor on the ground level of the house, which is causing our power bill to sky rocket. We are interested in getting an idea of what needs to be done in the crawl space, and any costs associated with that. Thanks
Spencer Street in St. John's
I would like to have a quote for a new sump with battery back-up.
William St. in St. John's
I live in a 120+ year old house with a dirt crawlspace floor. Every winter the floors above are freezing. As such, the living space above is also rather chilly in the winter time. Note there is little clearance between the ground in the crawlspace and the floor above. After a heavy rainfall, a small puddle of water is noticeable in the crawlspace. Looking for an estimate or quote to waterproof and/or insulate down there.
Suez in St. John's
Dear Colleague, My main purpose is to contact you to get quotation to complete unfinished concrete wall for part of the basement and to discuss possible basement development. Thank you kindly. Kind regards, Sanat
John Street in St. John's
Simple model sump pump installed in crawl space. Hone inspector recommendation. We are in the process of selling this property and the buyer wants this installed. There has been no flooding issue at all.
Kirke Place in St. John's
This older home was bought for our children while they are attending university and is not our family home. Our basement is unfinished and on any given day the dehumidifier will need to be dumped at least once. In wet weather this increases to three times over 24 hours. Without the dehumidifier mould and mildew forms on the floors. During last week with the heavy rains, water seeped up and puddled around the foundation posts located in the centre of the basement. This is the first time this has happened. Before we can put any living space there, the basement needs new windows and better insulation. I would like to ensure that the water issue is solved before investing any money to finish the space.
McNeil Street in St. John's
Have a crawl space in an older home that needs some professional attention.
in St. John's
Hello, I am looking at buying a house which has a pier and beam type foundation. The crawlspace has a dirt floor with insulation on the ceiling, but the exterior walls are just plywood. I would say the whole crawlspace is less than 1000 square feet. I was wondering if I could get a rough quote of what it would cost to insulate and encapsulate the crawlspace? Thank you so much!

Crawl space issue with rodents. Not sealed properly.
Braemere St. in St. John's
We currently have a dump pump in our bas meant but I don't think the water is being distributed properly. It may be causing concern in other areas.

Interested in an efficient sump pump system.
Foran Street in St. John's
Doing a renovation to put a ground level apartment for my parents. Part of the living space is over the crawl space in our split level home. It has dirt floor and no insulation, is dry but damp smelling....would like to make it more friendly for storage, warmer and cleaner! We are installing HRV with HEPA filter for the whole house, so makes sense to deal with other possible source of allergens while we are at it!!
