Built on Planning and Precision
Merman Construction builds home additions that feel like they were always part of the original structure. We work with families throughout Plymouth Meeting and Montgomery County who love their location but have outgrown their space. Every addition we build is planned carefully, permitted correctly, and executed by Steve Merman and his crew from first day to final walkthrough.
Why Plymouth Meeting Homeowners Choose Us
Remodeling in Plymouth Meeting requires an understanding of homes built across several decades. Construction styles vary widely from postwar ranches near Germantown Pike to newer colonials in Whitemarsh Woods, and each era presents its own structural considerations. We work regularly in neighborhoods throughout Plymouth Township and understand the zoning setbacks, impervious coverage limits, and building codes required by Plymouth Township to keep your project on track and on budget.
What sets us apart is not just local knowledge, it is the level of personal involvement Steve brings to every job. He is not a salesman who hands your project off after signing. He is on site daily, managing the work, communicating with you directly, and ensuring the quality matches what was promised.
From Start to Finish
We plan every project carefully so the build is smooth, predictable, and respectful of your home and your schedule. That means thorough pre-construction planning to prevent surprises, clean and organized job sites throughout, clear communication at every stage, and a final walkthrough where nothing is considered done until you are satisfied.
- Structural planning that prevents surprises
- Clean job sites and clear communication

Basement Renovation
A finished basement is one of the best ways to expand your home’s usable space and add long-term value. Instead of an unfinished storage or laundry area, your basement can become a welcoming extension of your home.

We have worked extensively in neighborhoods like Plymouth Valley and Whitemarsh Woods and understand what it takes to add onto these homes correctly. Steve Merman is on site for every project, not just the estimate.
Is a home addition worth it in Plymouth Meeting?

Customer Testimonials
“10/10 experience, with now a days prices Jana and Steve got us a GREAT and super competitive price! Not only was the price good, but the service to match it was better. Steve is SUPER diligent, master of his craft. Was able to analyze the scope of the project and the small intricacies from day one. Jana was super on top of it with telling us where we are at through the whole process and providing us interactive models of the extension AS it is being built. If you’re in the Chester county area I can’t see any other option than Merman!”
“I had an outstanding experience working with Steve and his team at Merman Construction. Their attention to detail is truly impressive—every part of the project was handled with care and precision, and the final results exceeded my expectations.
Steve is incredibly easy to work with. He communicates clearly, listens to what you want, and offers helpful suggestions without ever being pushy. His professionalism made the entire process smooth and stress-free.
The team was punctual, reliable, and consistently respectful of both my time and my home. Every day they showed up exactly when they said they would and kept the project moving efficiently.
I highly recommend Merman Construction. Steve and his team deliver excellent craftsmanship, outstanding service, and an overall experience that’s hard to find. I couldn’t be happier with the work they did.”
“Merman Construction completed a large construction project for us in 2024. The project consisted of a 28×30 garage addition as well as a renovation of the existing garage space to a mudroom and new laundry room. Steve and his team are true professionals and executed above all expectations. The entire process was handled professionally with attention to detail. Everything from Permits, drawings, material ordering, to execution on construction were handled amazingly. It was also refreshing to work with a contractor who didn’t always tell me what I wanted to hear. Steve offered constructive challenges to design ideas based on what he had seen work or not work in the past, as well as was openly honest when things just weren’t feasible. He treated our project as if it were for his own home. All change orders were clearly communicated and documented to minimize any confusion. I would absolutely recommend Steve and his team for any project big or small and we will use him in the future for sure.”
