At Allied Additions LLC, we specialize in the construction of high quality home extensions and room additions, as well as the installation of energy-efficient siding that insulates homes against weather and heat loss. We are uncontested experts in the design and construction of room additions that meet and exceed even the expectations of our most discriminating clients. Whether you wish to have your home addition look like it was planned from the beginning, or is a brand new architectural concept that makes your home unique, we can deliver results you can be proud of.


There are very few home extension specialists qualified to deliver results of the level of quality that we provide at Allied Additions LLC. The reason for this is that general contractors who may be used to building homes from scratch actually have very little experience in the highly specialized market of building home additions. The extra considerations that must be made in order to guarantee top-quality results are something that only our team of highly experienced professionals can provide. When you contact us for a home extension, room addition, or siding installation project, we begin the process with a comprehensive inspection of your home. This inspection allows us to determine exactly what kind of approach is most likely to provide you with the value you are looking for, and lets our technicians get to work on designing the best possible room addition to meet your needs.


Following the inspection and estimate, we immediately get to work on drafting possible variants for your home improvement project. If you choose to work with us, we can offer quick and comprehensive construction services that are guaranteed to offer durable, beautiful results. Have one of our inspectors visit your home today and find out how Allied Additions LLC can help you increase the value of your home!
