"The windows and doors are wonderful.  However the project took longer than promised.  
I will say, the company does beautiful work with regard to installation and sealing of windows, doors and overall craftsmanship..  I've seen what other companies have done to neighbors houses and the work was sloppy and they actually damaged the house.  That wasn't the case here!  

I did have a few problems with our sales person Cary.  I then I started dealing with Monica, the Operations Director, who got things done right and in a timely fashion..

Actually Cary, the windows which had to be changed at your cost of 1200 were windows that you ordered incorrectly  and and were not the windows ordered according to the contract, so yes, I required the correct windows be installed."

"It went absolutely amazing. We are remodeling our home, and Paver Concepts by far has been the easiest most professional company we have worked with. Their attention to detail and craftsmanship is second to none. We couldn't be happier with our new back yard. We would highly recommend them to anyone that needs any of the services the provide.  We have already recommended them to a few friends who also have had the same experience. 5 star company for sure."

Retaining Wall Installers FAQs, answered by experts

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.

Poured concrete is often the cheapest material for a retaining wall, costing around $6 to $8 per square foot. Other budget-friendly options include vinyl and landscaping timbers, which range from $10 to $15 per square foot; landscaping timbers are particularly well-suited for DIY projects. Untreated timber and railroad ties are a step up in price, starting at $15 to $25 per square foot. Natural stones can also be a cost-effective choice if you can source them from your own property, but they can be expensive to purchase. High-end materials like steel are typically the most expensive but offer superior durability and aesthetics.

Rebar is a steel support that goes inside concrete to prevent structural damage over time. Concrete is susceptible to impact, weight, and tension. By inserting rebar into the concrete during the installation, you can help extend its lifespan and avoid hazardous situations where the foundation of your home gives way to tensile forces.

Railroad ties can be good for retaining walls, but it depends on the area. They have a desirable rustic look and are durable. The problem is they’re treated with creosote, a preservative the EPA says poses a risk to humans and wildlife. Over time, the preservative seeps out of the wood and into the ground. Many areas have banned the use of creosote-treated wood on residential properties. If your area does allow it, never use railroad ties near an edible garden or drinking water source. Instead, use wood that’s treated with an EPA-approved preservative or a wood-alternative composite material.

While vinyl is the least costly material for building a retaining wall, the most cost-effective method is to use wood or concrete blocks for a DIY retaining wall under 2 feet tall. Wood is inexpensive but lasts 20 years or more with care. Concrete can cost a little more but is stronger and will last longer with less maintenance.
