"Jacob and Cody have been amazing to work with. We originally hired them to repair our stairs and have since contracted with them to install our kitchen tile floor, install electric in our kitchen island and to repair some of our drywall. Their team is very professional, their estimates are accurate and they do quality work. We plan to hire them again when we remodel our bathrooms."

"No matter what problem you have, Clint is the man for the job! He not only fixed the plumbing issues I discovered during a remodel but was able to fix the electrical issues, flooring problems, install the cabinets, cut and grout backsplash tile, and fix a handful of minor issues that came up along the way. Clint is on time, dependable, courteous and respectful of your property - he even cleans up afterwards! I could not have completed this project without Clint Hatcher and highly recommend him to anyone who needs work done - you will not be disappointed!!"

"I cannot say enough wonderful things about this amazing company! My daughter and I had been without a furnace for over 6 years. We used space heaters in the bedrooms, bathroom and kitchen, but the rest of the house stayed cold. Along with that, I had a constant fear of an electrical fire resulting from the units, because last year a young mother and her baby died in a house fire down the street from us, most likely caused from a space heater. When Schraer came to our home that offered to install gas furnace free off charge that was just sitting in their shop! We are truly Blessed and Grateful for their kindness and generosity! There are good people out there in the world, and the owners and employees of Schraer Heating and Cooling are some of best!"

"The father and son duo was very professional. My emergency happened after typical business hours but they still came out take a look at my thermostat. Very polite and informative. Once the store opened, they got what they needed and returned the next morning. They did an excellent job and are very affordable. I look forward to continuing business with them."

Nest Installation questions, answered by experts

In O'Fallon, if you notice live ants, termites, or spiders reappearing within a month after treatment, or find new termite mud tubes, chewed wiring, or fresh rodent droppings, it’s time to revisit pest control. Persistent mosquito activity, unexplained pet agitation, or water-damaged wood can also signal ineffective treatments. After heavy rainfall, check for washed-away barriers or reopened gaps around doors and windows.

Helpful?

In O’Fallon, keep a pump sprayer for perimeter insecticide applications, a bulb duster for attic or wall void treatments, and a moisture meter to monitor basements or crawl spaces. A sturdy inspection mirror helps spot pests in tight areas, while a caulk gun is essential for sealing gaps common in local brick or siding. Stock rodent bait stations and mosquito dunks for seasonal pest prevention.

Helpful?

For a seamless pest control project in O'Fallon, start by scheduling a termite inspection before peak swarm season. Identify and address drainage issues, and ensure all attic and crawl space access points are clear. Discuss any household allergies or sensitivities with your provider, and arrange for pets to be safely relocated during treatments. Plan for follow-up visits to monitor for recurring pest activity.

Helpful?

Before hiring a pest control pro in O'Fallon, document specific pest sightings and note areas with excess moisture or wood debris. Ask about experience with local pests like termites and mosquitoes, and request details on treatment safety for children and pets. Clear out storage from crawl spaces, trim back landscaping near your foundation, and confirm the provider’s scheduling flexibility to avoid unexpected disruptions.

Helpful?

O’Fallon homeowners are choosing low-visibility, tamper-resistant bait stations that blend with mulch beds and native plantings. Integrated pest management is popular, with a focus on eco-friendly sprays and smart monitoring devices that send alerts about activity. There’s also a trend toward using river rock landscaping to reduce harborage for pests and installing mesh screens on vents to prevent rodent entry during colder months.
