How to Seal Cracks Around Your Home

If you noticed a crack in a window, mirror, or floor tile, it would be obvious enough that you would want to address the issue sooner rather than later. But what about the cracks in and around your home that may not be as apparent?

These are the openings that have the potential to create more problems for a homeowner. In the summertime, cool air can leak out and make your AC work harder. And in colder months, not only will warm interior air escape outdoors, but moisture can form inside concrete cracks and possibly freeze, which will widen these gaps and exacerbate the damage. In other words, these less-noticeable cracks are the ones which should be sealed promptly.

Cracks in Driveways and Sidewalks

The cracks and crevasses in the pavement around your home can present ongoing safety hazards for guests and visitors. Often, they are less than a half inch in width and can be fixed using Portland cement or a vinyl crack filler. Just be sure to clean out any weeds, dirt, or other debris before applying the sealant, and perform these repairs on a warm, dry day to allow the substance to seal properly.

Larger cracks will require the use of flexible polyethylene backer rod, play sand, and self-leveling elastometic caulk. After cleaning the area, pour the sand into the crack and tamp it down (or drive over it), leaving about 3/4 of an inch from the top of the slab. Then lay the properly-sized backer rod atop the sand so about a 1/4 inch of space remains. After cutting the tip of the caulking gun to fit the gap, apply the caulk over the backer rod and allow to dry.

Cracks in Walls or Slabs

Minor cracks in these areas can also be sealed by hand (if the cracks are abundant and/or major, call a structural engineer to see if foundation repair is needed) with a liquid concrete repair kit that contains several components. After scrubbing the entire crack clean and removing the dust and debris, tap 3-inch finishing nails into the crack a foot apart. Mix the two types of epoxy crack sealer together on a board and use it to attach a plastic injection port over each nail. Then using a margin trowel or putty knife, liberally apply the sealer over the entire crack, including the port flanges.

After letting the substance cure for six to ten hours, inject liquid concrete repair into each port using a caulk gun until it seeps out of the next port. Then insert a cartridge tip into the “oozing” port and squeeze the trigger to disperse the sealant, and then plug it up. After repeating this process which each port and waiting five days for the caulk to set, saw off each port neck using a hacksaw.

Cracks in Other Parts of Your Home

Finally, there are cracks, gaps, and openings that can be found all around your home wherever you see a break in the walls. Use aluminum flashing and caulk to seal openings around chimneys and flues. Your attic hatch can be sealed with caulk or foam weatherstripping. Baffles and sealant should be applied around gaps in recessed lighting, electrical outlets and boxes, or light switch boxes. If you have a basement, seal cracks with spray foam or caulk.

Repairing these cracks on your property can usually be done without the aid of a contractor if desired. And it’s a cost-effective way to lower your utility bills, boost curb appeal, and fortify your residence against moisture and other elements. So don’t fall into the “out of sight, out of mind” mindset; be proactive and seal these cracks whenever possible.

I have had Gutter Helmets for 20 years. In all that time I've never had a problem until recently a bird's nest found its way into one of my gutters. The installer who came to replace the product was the same installer from 20 years earlier. Now that's impressive. Everyone at Gutter Helmet inclusive of the office staff were professional and a pleasure to work with.

Gutter Helmet by Harry Helmet just replaced our roof and we could not be more satisfied. The crew showed up early, worked all day and stayed late, were professional and caring regarding the project and the surrounding impact it had on our property and home. They completed the roof quickly and it looks simply amazing!

VERY happy with our entire experience adding Gutter Helmet by Harry Helmet to our house. Installing this was a great value for us. The gutters are working perfectly in heavy downpours and with year-long leaves and debris coming down from our river birches. Terrific customer service and a first class product.

We needed our roof repaired due to wind damage. After several quotes, Gutter Helmet was the only company that went into our attic to look and see if more damage had occurred. If it wasn't for them taking the extra time to look at everything, we would have had rotting wood under our new roof. They were very professional and gave a fair quote.
