Upper Eashing Window Mastic
Our applicators work in Upper Eashing on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Old mastic that has gone black or come away
- Leaking joints at the ends of sills
- Gaps between the frame and the inside reveal
Surface by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
About our window mastic in Upper Eashing
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on uPVC windows, composite doors and patio & French doors, and the jobs we see most are old mastic that has gone black or come away and whistling draughts around closed windows.
In a village or hamlet like Upper Eashing, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

What affects the cost of window mastic
Your quote is based on your job. We take into account:
- Any working-time requirements on site
- The amount of work
- Access and height
- Which sealant suits the joint
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- Pictures of the joints, sent by email
- The type of property
- Where the property is

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A sash or casement that will not close properly
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before booking.

The process
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. In a small place like Upper Eashing, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Mention any tricky access

Your questions about window mastic in Upper Eashing
Can you do window mastic in Upper Eashing?
Yes. We work across London and the South East, and Upper Eashing is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Can you help a landlord with a rental near Godalming station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Can I paint over the new sealant?
Not generally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
How do I get a quote for window mastic in Upper Eashing?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

What else we do in Upper Eashing
Why act early in Upper Eashing
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Where a wall is exposed, as many are in small places like Upper Eashing, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What you get with us
- More than 20 years in sealant work
- You choose the colour before work begins
- White, clear, grey or another colour, product permitting
- Anti-fungal silicone where joints get wet

Upper Eashing homes and the weather
Historic houses like Loseley Park (about 2.7 miles north-east) are a reminder that the area around Upper Eashing has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you live in an older home near St Mark's Church and Community Centre, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as St Mark and All Saints Church of England Primary are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Godalming station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
