Internal & External Doors
We offer an extensive selection of internal and external doors, from traditional timber designs to cutting-edge modern materials like composite and aluminum. Each option is chosen for its durability, security, and style, allowing us to match the right door to the character of your home.
Sash and Bi-Fold Windows
Windows are an integral part of both the appearance and performance of your home, and at OLS Building Services, we provide expert installation of sash and bi-fold windows and doors, tailored to your specific needs.
Custom Openings and Fitting
At OLS Building Services, we don’t just install doors and windows—we also handle all the structural work that goes into creating or adjusting the openings to accommodate your new fittings. Whether you’re replacing an existing door or window or creating a completely new opening, we manage the entire process from start to finish.
