Your Neighbors in Collinsville

Collinsville grew up as a coal town. Mines ran here from the 1850s until the last one nearby closed in 1964, and many of the homes built for those families still stand around Uptown and Main Street. Postwar neighborhoods filled in after that, and newer homes keep going up on the edges of town.

Older homes mean older drain and sewer lines, and our techs know what to look for. Whether you need a drain cleared, a furnace replaced, or a panel upgraded, GRP|WEGMAN brings union-trained techs, honest flat-rate pricing, and a phone that’s answered 24/7. We’ve been part of the Metro East for more than 70 years, and Collinsville sits right in the middle of it.

Common in Collinsville Homes

The age of your home tells us a lot about what it needs.

Uptown HOMES

Homes near Main Street and Uptown go back to the early 1900s. Many still have original drain and sewer lines, older piping, and heating systems that were swapped out more than once over the years. We take our time in older homes and explain what we find.

Postwar Neighborhoods

Homes from the 1940s through the 1960s are solid, but their original drain lines and sewer laterals are now 60 to 80 years old. Slow drains and backups after heavy rain are common signs it’s time for a closer look.

Established Homes

Homes built in the 1980s and 1990s are often on their second furnace and AC, and some are due for a third. If yours is 15 or more years old, it pays to plan a replacement before it fails in the middle of a heat wave or cold snap.

Newer Homes

Newer homes need less, but not nothing. Regular tune-ups keep manufacturer warranties valid and catch small problems early. The At Home Club covers spring and fall.

What Our Neighbors Say

“

They were here the next day and had my air conditioner in and I had air that night.

“Our AC had went out... I called and they got it all set up and they were here the same day to evaluate the situation... It's so quiet you can't even hear it... fantastic guys, very courteous, very professional, explained everything about the whole unit. It was just a very fabulous experience with us.”

Still have a question?
Call 618-258-9000, 24/7.

Do you serve all of Collinsville, including the St. Clair County side?

Yes. Collinsville sits in both Madison and St. Clair counties, and we cover every part of town, from Uptown to the newest neighborhoods. We also serve Maryville, Glen Carbon, Edwardsville, and the rest of the Metro East.

Do you work on the older homes in Uptown?

Yes. Many homes near Main Street are more than 100 years old, with original plumbing and heating that has been updated piece by piece. Our techs figure out what you have before recommending anything.

My drains back up after a heavy rain. Can you help?

Yes. In older homes, backups after rain often point to an aging sewer line. We’ll clear the drain, inspect the line, and give you an honest answer on whether it needs a repair or just regular cleaning.

Is my home on old mine ground?

It might be. Much of Collinsville was mined for coal, and the state offers a free map where you can look up your address. If you’re noticing new cracks in concrete or slow drains you can’t explain, give us a call and we’ll check your plumbing lines.

Do you handle permits in Collinsville?

Yes. When a job needs a permit, we pull it and take care of the inspection, so you don’t have to deal with the paperwork.
