Local sliding sash windows installers in Brentwood
The 1930s semis around Shenfield and Hutton, and the newer builds in Warley, are our most-fitted Brentwood postcodes.
We've been fitting sliding sash windows across Brentwood for over 25 years. Every install starts with a free home survey where we measure up, talk through the glass and frame options, and give you an itemised fixed-price quote before you commit to anything. No high-pressure sales, no vague "from" pricing that changes on the day — just an honest local quote.
Once you're happy, we place the order with our approved UK manufacturers. Lead time is typically 4-6 weeks depending on specification. Fit day is usually one day per opening for windows, and we take away and dispose of the old frames.

- Tilt-in feature for safe internal cleaning from inside
- Concealed constant-force balances (no cords, no counterweights)
- Approved for many Essex conservation areas as timber alternative
