We make it. We install it. You save.
National replacement brands price broadcast ads, appointment setters, commissioned closers and a discount that expires tonight into the number they quote you. We don't carry any of that. We manufacture in North Charleston and sell factory direct.
- The right product, not just ours. If another manufacturer suits your home better, that's what we'll specify.
- Tested by real hurricanes, not lab simulations. Our installations have been through multiple storm cycles.
- A showroom you can walk into. See and handle the product at 1930 Hanahan Road before you decide.

What customers say
Lowcountry homeowners,
in their own words.
From 83 reviews on Google and more on Facebook and Yelp.
Ours was a large project, 54 hurricane rated windows and 2 entrance ways. The installation crew was considerate of our home and cleaned up where they had been working each day.
I bought two windows that had to be custom made because of an odd size. The new windows went in easily and look and work great. I will absolutely use The Muhler Company again.
We would highly recommend Muhler! We had a window that was leaking and needed to be replaced. Muhler was the only company out of 5 I called that would do just an individual window.

Engineered for the coast
Proven by the storm,
not by a brochure.
Salt air, wind load, flood zones, humidity, and a code that has changed many times since 1992. We've installed through all of it, in this market.
Coastal code and permits
Wind zones, flood elevation, HOA review and Charleston's historic district rules. We handle them.
Impact and opening protection
Rated systems that qualify for wind mitigation credits, with the paperwork your insurer wants.
Built for humidity
Water management designed into the frame, because in the Lowcountry that's what fails first.
Questions
Before we come out.
How much do replacement windows cost?
It depends on size, style, glass and how many openings. The estimate is free and in writing, so you'll know the exact number before you decide anything.
Do you only sell your own windows?
No. We make our own line and carry others. If another manufacturer suits your home better, that's what we'll recommend.
Can you replace just one or two windows?
Yes. Small jobs are welcome.
Do you handle permits and HOA approval?
Yes. Wind zones, flood elevation, HOA review and Charleston's historic district rules are part of the job, not your problem.
Is there any cost or obligation for the estimate?
None. It's free, and there's no deposit.
