"Having our house completely refurbished by Blacklough Construction was an incredible experience.

They exceeded our expectations in every way, bringing our vision to life with meticulous attention to detail.

"Imagine hiring and going through a complete 2 family renovation any day or time of the year – What stress. Now add COVID. Our renovation was right in the middle of it. Fortunately for us we made the right decision with Blacklough and Gavin and his team. Construction has its obstacles and COVID added many more with supply chain issues, price increases, COVID protocols for the trades coming and going in the house. Gavin never missed a beat. We were able to navigate through it all and in ten months did a complete 2 family interior renovation with 6 bedrooms, 2 kitchens, 5 bathrooms and everything else in between. What impressed me the most was the level of communication that we had through this process. This was critical to stay on time and to keep the project moving forward. For us choosing Blacklough was the best decision we made when selecting a contractor. If integrity, quality craftsmen and attention to every detail are important. Look no further – Blacklough is the choice.”
-The Bayer Family
