Professional Solutions

Affordable Foundation Crack Repairs

SEALED technicians are experienced professionals who will find the right solution and do the job right. We are sticklers for being thorough, and we work on your schedule to make things as convenient as possible.

Crack Injection Sealant

Let SEALED help you to stop or prevent leaks in your basement foundation walls, because a dry basement is a healthy basement. SEALED has assisted hundreds of Kansas City homeowners to make their basements dry and healthy.

Carbon Fiber Repairs

For larger cracks SEALED often recommends a Carbon Fiber Strap or Rhino Concrete Crack Locks embedded in epoxy. Our repair will stop leaking and can help prevent any further wall movement, because carbon fiber is stronger than steel.

Carbon Fiber Crack Locks

SEALED can repair a bowed wall with carbon fiber straps and steel braces bolted to the floor joists. This repair can be accomplished on both poured and concrete block foundation walls.

Rusted Rebar Repair

Rebar is short for “Reinforcing Bar” and these steel bars are used in concrete construction to add strength and prevent cracking in concrete that supports heavy weights. Rebar will be found in residential foundations to help the walls support the weight of the home.

I couldn't recommend Randy more! Sealed will do everything they can to get your foundation problems taken care of. He's very timely and does excellent work!

Randy did an amazing job. Extremely competitive pricing. Time between our initial call to request a quote and completed repair was only a week and a half. Randy took the time to explain to us what he was doing and why. Repair came with a transferable warranty. Would completely recommend and use again for any other cracks we discover.

Sole proprietor who knows his business.
Dan Bacon 7/28/2020
Randy does an OUTSTANDING job. He fixed a crack in our basement 3 years ago, and due a manufacturing default, the crack began to leak again. He came back out, took off the old seal and used a different type, which works great! He must have spent 20 hours down there, free of charge. He said it was all covered under his warranty. GREAT GUY. WOULD USE AGAIN.

Randy with Sealed is the epitome of professionalism with heart. He listens to the client, assess the situation with expertise and provides affordable solutions to meet the need. I feel 100% comfortable referring my Real Estate Clients to Randy whenever they have foundation questions. Excellent service!
Rebecca Graham 5/17/2021
Sealed LLC was excellent to work with from first contact through completion of the crack sealing work in our concrete basement wall. We had a crack that persistently leaked after several attempts by us to repair the crack. Randy was deliberate in the preparation of the crack area, in application of the "pre coat" to contain the sealant, and in the injection of the sealant. The procedures for using this process were diligently followed. Precautions were also taken to minimize dust resulting from the crack preparation process. This was a very satisfactory experience. There have been a number of rains, and there has been no leakage.
S Huntoon 8/11/2017
Randy did an excellent job repairing the crack in our basement. His attention to detail and precision in cleaning the surface and walking me through the steps of what he would be doing to waterproof the structure showed me true mastery of his field. I highly recommend Randy for his personal attention and knowledge of how to fix the job at hand, and from what I know of him, if the work is not in his wheel house, he has a referral network which can get any manner of basement repair done. Great job Randy!

Frequently Asked Questions

We’ve answered many of your commonly asked questions about our services in general, and specifics about our foundation crack repair process.

How Much Does SEALED Charge To Repair A Crack?

It depends on several factors including the length, width and amount of wall preparation required. Most single cracks cost less than $500 for polyurethane injection. Carbon fiber repairs are a bit higher. But don’t worry, SEALED offers free inspections and estimates, so it doesn’t cost you anything to have us take a look.

What causes foundation cracks?

An assortment of things may cause poured foundations to crack. Settling, especially after several decades; wide temperature fluctuations in the ground; the presence of clay in the soil; and sometimes the quality of the original work are all common reasons for cracks.

How long do SEALED's repairs take?

In most cases we can be done in just a few hours. But for homes with multiple cracks it could require two visits.

How long will I have to wait for SEALED to begin the work?

We set our appointments around your schedule and in most cases we can begin within a few days of our inspection.

What needs to happen before SEALED begins?

All material covering the crack must be removed including drywall, paneling, wallpaper, shelves, and studs. And if necessary, SEALED’s estimate will include the time required to remove any previous repair.

What if I see water from a crack after SEALED’s repair?

Our work on polyurethane injection and carbon fiber repairs on poured foundation wall cracks carries a ten year warranty against leaks. In addition, the warranty is fully transferable in the event you sell your home.

When do I need to pay SEALED?

SEALED get paid when the work is complete. No deposit is required. And we accept cash, checks and credit/debit cards.
