About LandMark

Noticing the lack of customer service and quality of companies in the industry, Paul O’Meara and John Long decided to start a company in 2004 that would stand out in terms of service, quality, and overall reputation. Their vision was to provide customers with an all-around pleasant experience and provide them with quality products/service at reasonable prices. They offer a no-pressure sales appointment and make solid suggestions based on a customer’s needs and/or budget. John and Paul take pride in the way the LandMark team conducts business and continually strives to enhance their customers’ experiences.

Elevate Your Home to LandMark Status!

We have the premium products your home needs to increase value and add curb appeal.

What's it like working with us?
quote 2

“Working with LandMark was one of the easiest decisions I’ve ever made. First off, I saved a bunch of money going through them (literally 30% cheaper than local competitors) Second, my roof was completely replaced within three weeks from when I signed the contract. The whole process from soup to nuts couldn’t have gone smoother! Recommend them x1,000! Thanks, John!!”

This was by far the best experience I have ever had with an installation project. While installing the sliding glass doors the workers were so conscientious of protecting the floors and surrounding walls. When they completed the job they made sure everything was disposed of and the floors cleaned. The caulking around the door was done perfectly. After the door was installed within 20 minutes another worker arrived to do the finishing work on the frame; filling in nail holes and applying the final finish. In addition, prior to the installation, Landmark took great care to make sure the new frame around the door would match as closely as possible to the existing woodwork in my home.

Landmark installed windows, a patio door, and our front entrance door. We are very pleased with the quality of the Marvin and ProVia products. The Landmark installation team did a great job. They were friendly, efficient, and very respectful of our home. Our salesman, Greg, was very knowledgeable and was able to professionally answer all of our questions. The purchasing process was very pleasant and hassle free. I would strongly recommend Landmark and will use them for our future home projects.

LandMark Exteriors replaced all the windows in our home with Marvin Infinity windows. From start to finish our experience with them has been excellent! Our sales representative walked us through the various options we had, answered all of our questions thoroughly and we ultimately decided upon the Marvin windows as the best option for us. We were kept updated throughout the process leading up to installation so at the time of the installation we had plenty of time to prepare. The installers did an amazing job and kept us informed as to how the job was progressing. Every project has some unexpected surprises and the crew handled those with precision and care to ensure the job would be perfect. The followup after the installation has been just as incredible to address any concerns we have had. The entire LandMark team has been professional, courteous and strive to provide the best customer experience possible, I highly recommend them!

I am very happy with LandMark Exteriors, Inc. I have both front, back and storm doors replaced. Mike Kerr - the sales representative was simply wonderful - profesional, knowledgeable, patient and offered his best advice. Without Mike, I would most likely end up with different type of doors that wouldn’t be as great as the ones that were just installed. Also, the installers - Mike and Adrian were great - experienced, diligent, and super nice. They made sure that the job was done correctly. And, finally - Krzysztof, the painter - he painted all the frames that had to be replaced and he did his job perfectly! I couldn’t be luckier to have worked with such in readings team! I highly recommend LandMark Exteriors, Inc. because they are the BEST!

All details taken care of. After starting discussions with other companies and not hearing back from many and never being able to get estimates from them, we met with LandMark and everything went smoothly from there. The work was done quickly and well. No issues.
