How the job changes by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How the visit works
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a single window, longer for several. In a small place like Egham Wick, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.

Before we arrive

How long does sand mastic take?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Bigger jobs take longer, and we will say how long yours will take.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Get any rot dealt with first
- Ask us before painting near the mastic
- Find out about consent before window work on a listed home
- Look over the window mastic once a year
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.

Egham Wick homes and the weather
With historic houses such as Frogmore House (about 3.6 miles north) nearby, there’s older building stock in the area around Egham Wick as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Virginia Water station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Managing a site like St Cuthbert's Catholic Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of Saint Simon and Saint Jude include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
