Keeping a close eye on the state of your crawl space is not the easiest feat—especially if you need to get on your hands and knees to access its contents. When troubles arise, hiring the right crawl space contractor can be a game-changer for your home's comfort and longevity. 

Whether it's time for a crawl space cleaning, repair, or encapsulation, here's how to find a crawl space contractor that meets all your criteria.

How to Find a Crawl Space Contractor

The key to finding the best crawl space contractor is giving yourself options. Not every crawl space expert will be right for the job at hand. For example, you may need to ask around to find a crawl space contractor who cleans crawl spaces. 

In other cases, local crawl space and basement waterproofing professionals are your best solution. As you research crawl space contractors either online or ask for referrals from neighbors, choose at least three pros to compare their backgrounds and prices.

Jump into your crawl space research by getting to know more about your project, what to expect from the costs, and the necessary qualifications of a good contractor.

1. Plan Your Crawl Space Project

Crawl space issues can creep up in several ways. Foundation cracks, old support beams, and even pests can all be causes for repair. Additionally, cleaning and waterproofing your crawl space can improve your home's air quality and even control heating bills in the winter. Some of the most common crawl space jobs include:

  • Encapsulation

  • Cleaning

  • Pest control

  • Support beam replacement

  • Foundation crack repair

  • Water damage remediation

  • Mold removal

  • Insulation repair

  • Vapor barrier repair

If you know that issues in your home stem from your crawl space, but you're not quite sure what you'll need, a professional can provide more details during your initial inspection.

2. Estimate Costs and Insurance Coverage

Crawl space cleaning and repairs can cost anywhere from $250 to $15,000. The type of tools and level of expertise needed for the job will heavily sway the price. Additionally, it's important to check your home insurance plan and home warranty to see if the type of damage falls under your coverage.

3. Check Your Crawl Space Contractors Qualifications

Crawl space contractors and local basement waterproofing professionals should be able to show proof of their experience, license to work in your state, and liability insurance. Many crawl space companies also offer workmanship guarantees. A great contractor will also understand your local crawl space building codes and know when to obtain a permit.

4. List Out the Questions for Your Crawl Space Contractor

Now that you have a better sense of what to expect from your first meeting, write up some possible crawl space questions before interviewing your pros.

  1. Do you perform crawl space inspections?

  2. Do you offer free consultations?

  3. What is your work experience with crawl spaces?

  4. Do you have customer testimonials on your work?

  5. What is your contract process and payment structure?

  6. Is there an estimated length of the project?

  7. How would I need to prepare the crawl space for your visit?

Hiring a Crawl Space Contractor Tips

It's time to jump into your crawl space contractor search. Here's what to know about hiring the best crawl space specialist for each unique job.

1. Interview Multiple Crawl Space Contractors

We always recommend interviewing at least three contractors before signing an agreement. Don’t just opt for the contractor that offers the lowest price, either. It's important to clarify your crawl space contractor's costs as well as whether they offer a binding estimate for their work. They should also be able to answer any specific questions about your crawl space as well as big-picture questions, such as whether crawl space encapsulation adds value to your home.

2. Arrange a Crawl Space Inspection

Many crawl space jobs will begin with an inspection. The service should be a part of your annual crawl space maintenance, especially if you live in an area prone to pests or mold. Chat with your contractor about whether a consolation or basic inspection comes with the cost of the repair. 

3. Sign a Contract and Clarify Payments

Always sign a contract for crawl space repairs and all other major projects before they begin. Be sure to clarify if your contractor requires a down payment and what type of payment method they prefer. Always check if the price can or will change as they perform their work. 

Keep in mind that many large projects, such as turning a crawl space into a basement or repairing foundation issues, may require a more complex payment schedule and contract.

4. Keep Records of the Progress

Take photos of your crawl space before, during, and after the contractor works whenever possible. Keeping visual records and discussing progress with your professional will help you clarify any issues that arise later. While this will hopefully never be the case, you can use this information should you need to discuss work errors.

After Your Crawl Space Contractor Finishes

Discuss whether your crawl space contractor offers cleanup at the end of the job. Once they're finished, settle your bill and take pictures of their work. It is also important to speak with your pro about maintaining your crawl space. They may recommend controlling the humidity, keeping it clear of large debris, and watching out for signs of pests or water damage.
