Would like an estimate on crawlspace insulation (spray foam or other). Currently have fiberglass insulation with poor to non-existent vapor barrier.

Looking to insulate a crawl space.
Vicinity of Julieann Place in St. John's
We just bought a cabin in Middle Gull Pond. It is on concrete block foundation with a crawl space. Floors are cold and electricity bills are high. There doesn't appear to be any insulation or vapor barrier in the crawl space. The wood underneath is in good shape but there is evidence of some moisture on the ground of the crawl space. Inside there is evidence of movement with uneven floors and some dry wall cracking. We are wondering what we can do to make the cabin warmer and more energy efficient.

Sub pump no longer working. Causing excessive moisture
Vicinity of Allan Square in St. John's
I have a frozen pipe towards the rear of my house. There is currently vapor barrier on the dirt portion of the basement/ crawl space but it's hard to know it was done properly becasue it was done by a previous owner. I'd like a quote on insulation for the floor and to stop the air leaks. It's probably easier to explain over the phone. I need a quote on insulation and a possible quote for insualtion and possibly the vapor barrier. Thanks!

I previously had a sump pump installed by your company and would now like to have waterproofing and insulation to fix cold damp musty basement. I can be reached best by email.
Vicinity of Pennywell Road in St. John's
I need 7 jack posts installed in my crawlspace, and possibly the lamination of 2 beams.
Vicinity of 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.
Vicinity of 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.
Vicinity of 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!
Vicinity of 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
Vicinity of 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
Vicinity of Spencer Street in St. John's
I would like to have a quote for a new sump with battery back-up.
Vicinity of 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.
Vicinity of 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

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.
Vicinity of 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.
