"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"We hired Master Remodel & Construction after our master bathroom, kitchen and garage suffered major water damage after an interior flood caused by an overflowing toilet. Brian Inkley (owner) and Jacob Quick (project manager) have a team of dedicated, talented professionals. They did a superb job in restoring our damaged house. They are a busy team of workers who kept us appraised of their availability for the various stages of our restoration. For the repairs that they didn't do themselves they had excellent recommendations for the professionals we needed such as the carpet installation, closet system installation, kitchen cabinets and the refinishing of our hardwood floors. They seem to be in demand, working at several projects at the same time but we always felt that we were their top priority. Jacob worked with our homeowners insurance adjuster to be sure that the funds allocated for our losses were enough to complete our projects. We recommend Master Remodel & Construction with pleasure."

"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 FAQs, answered by experts

In St Louis, homes with stone or brick foundations, especially in historic districts, often have hidden gaps that pests exploit. Finished basements, crawl spaces, and attached garages create concealed entry points. If your property features multiple additions, split-level designs, or intricate rooflines, these areas can trap moisture and provide nesting spots, making thorough pest management and inspection more challenging for local professionals.

Helpful?

Pest control in St Louis may require sealing around HVAC ducts, electrical wiring, or plumbing lines. If your home has blown-in insulation or older electrical systems, treatments in attics or basements could disrupt airflow or wiring. Before any pest exclusion or chemical application, discuss your home’s layout with your provider to ensure HVAC, electrical, and plumbing systems remain accessible and protected throughout the pest control process.

Helpful?

If you spot new pest droppings, chewed insulation, or recurring ant trails after rain in St Louis, previous treatments may be failing. Persistent mud tubes on foundations, wasp nests reappearing, or bait stations that remain full are red flags. Seasonal upticks in rodent or mosquito activity, especially after recent service, suggest exclusion work or barrier treatments need to be revisited for lasting pest prevention.

Helpful?

When hiring pest control pros in St Louis, look for experience with local pests such as termites, ants, and rodents. Choose professionals who provide detailed inspections, tailored treatment plans, and eco-friendly options if needed. Check for strong customer reviews, clear insurance coverage, and transparent guarantees. Reliable pros will also offer follow-up visits and advice on preventing future infestations, ensuring long-term peace of mind.

Helpful?

In MO, finding termite mud tubes on foundation walls or piles of sawdust from carpenter ants can indicate hidden wood damage. Water stains or musty odors in basements may signal leaks that attract pests and promote mold growth. If you notice rodent gnaw marks on wiring or insulation, address the issue promptly to avoid costly electrical or HVAC repairs and prevent further structural problems.
