Velux Windows Fitting

Lees Building Contractors Ltd offers expert Velux® roof window installation, enhancing natural light, ventilation and energy efficiency in loft conversions, extensions and existing roofs. Our portfolio features a variety of Velux® models—standard top‑hung, Cabrio® balcony windows, sun tunnels and blackout‑blind systems—tailored to each client’s needs.

Key Works & Features

• Site Survey & Roof Assessment
  Laser‑measured openings, structural check of rafters and precise templating to ensure perfect alignment and weatherproofing.

• Velux® Window Selection
  Supply and fit of any Velux® product—PVC or timber‑finish, electric or solar‑powered operation, fixed or opening variants, and a range of glazing options (toughened, acoustic, self‑cleaning).

• Precision Installation
  Cut and frame roof openings, install Velux® flashing kits (EDW, EDL, EFW, EHD) compatible with slate, tile, metal or flat roofs, and integrate insulation and vapour barriers.

• Interior Finishes
  Reinstatement of plasterboard reveals, application of moisture‑resistant finishes, bespoke timber lining kits and seamless trim details.

• Optional Upgrades
  Electric blinds, blackout blinds, sun‑shading awnings and remote‑control operation for enhanced comfort and privacy.

Specialist Techniques & Materials

• Structural Reinforcement: Timber sole plates and double trimmers where required to support larger aperture windows.

• Thermal Performance: Installation of Velux® ThermoTechnology™ insulated flashings and pre‑manufactured insulation collar for U‑values as low as 1.0 W/m²K.

• Waterproof Flashing Kits: Manufacturer‑approved flashings tailored to roof material—EDW for tiles, EDL for slate, EFW for metal, and EHD for flat roofs.

• Air & Vapour Barriers: Integrated airtight tapes and vapour‑control layers to maintain roof integrity and prevent condensation.

Why This Service Stands Out

• Certified Installers: All Velux® windows fitted by our FMB‑accredited team, ensuring compliance with warranty and British Standards.

• Custom Solutions: Whether you need a rooflight to brighten a hallway or a Cabrio® balcony for a dramatic loft conversion, we match the right product to your project.

• Weather‑Tight Guarantee: Manufacturer warranties backed by our workmanship guarantee—no leaks, drafts or thermal bridging.

• Turnkey Delivery: From window supply to interior finishing, Lees Building Contractors Ltd manages every stage for a hassle‑free install.
