What we are called out for in Egham Wick
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
The problems people usually mention when they call are:
- Whistling draughts around closed windows
- Old mastic that has gone black or come away
- Gaps between the frame and the inside reveal
- Sealant in the wrong colour for the frame
For site and facilities teams at buildings such as St Cuthbert's Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- What the cure time is
- Who does the work, and how experienced they are
- The length of the guarantee
- Whether the sealant suits the joint
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What happens if it’s left?
Resealing frames is a short job: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Egham Wick, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Anti-fungal silicone where joints get wet
- 180+ five-star Google reviews

Frames and glazing around Egham Wick
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Frogmore House (about 3.6 miles north) are a reminder that the area around Egham Wick has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Virginia Water station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of Saint Simon and Saint Jude, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Around Egham Wick
Around Egham Wick, our work takes us to homes and buildings near Riverside Walk and The Barley Mow Public House, among other places. For rail, the closest station is Virginia Water station, roughly 1.8 miles south-east of the centre. Nearby you’ll also find Spelthorne Museum (3.2 miles east) and Windsor Castle (4.3 miles north). For a walk, there’s Gracious Pond and St Ann's Hill.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
- Don’t aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. Somewhere like Egham Wick needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in

How the job changes by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
