Our Reputation Means the World to Us

Superior Quality & Incomparable Craftsmanship

At Kentstruction, we guarantee home extension projects of world-class craftsmanship and unparalleled attention to detail. Our team takes the utmost pride in delivering only the best for all of our clients in Long Island. We appreciate the way in which the longevity and aesthetic of our projects reflects on the quality of our craftsmanship – and we’re dedicated to preserving that sentiment.

Collectively, our team of architects, designers and contractors share several decades of experience in the construction and renovation business. What’s more, we only hire industry-leading professionals and thereby offer the most insightful, talented craftsmen in the field.

Our roster of expert architects design modern, sophisticated renovations by rendering the proposed floor plan in CAD (computer aided-design) in 2D and 3D – allowing you to both visualize your new interior or exterior home addition, and request any updates as you deem fit. This serves to ensure that the specifications of the home addition are agreed upon to the very detail before the renovation begins – eliminating any unnecessary costs down the line or misappropriated time.

We are home builders as well as design and architectural experts – servicing residential renovation jobs affordably and cost-effectively – with an easy customer experience from start, to finish and beyond.
