"I highly recommend this contractor. They were highly professional in every way: they always came just when they said they would, they did exactly what they said they would, they were great at solving problems that arose during the basement waterproofing project, and they did a really good job of keeping us informed multiple times a day about the progress of the project. The crew that handled our project was outstanding. We were especially appreciative of the work done by the foreman, Dan. Just great all around work."

"John from Global Dwelling did our initial assessment. I appreciated him taking time to explain all the work that needed to be done and why. His team came in a few weeks later and were really amazing. I think insulation work is super messy and will leave a ton of debris everywhere. I was pleasantly surprised to find a ton of cloth coverings coming in to cover everything and found no major dust/debris in the house when they were done. The guys were very nice and thoughtful while in the house. The work completed was completed on time and our house is definitely more comfortable. Our finished basement is no longer a freezer and the house doesn’t “sneeze” when there is a high wind. I have already recommended them to my neighbor for when he’s ready to insulate his attic!"

You can see that we've insulated and air sealed the rim joists in this picture in addition to the B2B paneling.
You can see the main attic ducts have been spray foamed in this photo.  This keeps the warm air warm as it travels through your cold attic in the winter time.

"High Tech recently re-brownstoned the co-op that I live in on 83rd Street and did an amazing job.  The price that we got from High Tech was about half of what we were quoted from the next lowest bidder, but the work ended up being so beautiful that people walking by our building are stopping to take photos.  High Tech reconstructed all of the old brownstone details that had been worn off and totally lost over the years.  These guys were artisans and asked me for very old photos of the building, which they used to re-create the designs of the building details.  It took a bit longer than I expected but It turned out so great!!!  I never expected that they could bring our building back to it's former glory, especially given the reasonable price.   Come walk by and take a look.
A couple of years ago High Tech had done our stairs, which also came out beautiful.  They got the detail right on that too.  The brownstone stairs look so nice, they have rounded edges like the most expensive brownstones have.  But again High Tech's price was the most reasonable of the bidders.  The have also done some other smaller jobs for us such as re-pointing and again I was very satisfied with both the quality of the work and with the price.
Oh, I almost forgot.  The electric company did some work on our block and chipped tiny bits off of the new stairs and High Tech came and repaired it at no cost.  I was very impressed with that since it totally above and beyond.

Basement Waterproofing FAQs, answered by experts

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.
