Window mastic in Epsom, done properly
Around Epsom we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on timber windows & doors, composite doors and aluminium frames, and people most often call us about rushed sealant from a window installation and gaps where the sill meets the wall.
In a town like Epsom, older houses sit alongside newer estates, with windows of every age. All of them depend on a sound bead of mastic between frame and wall.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Keeping the joints in good condition
So the new joints stay in good condition:
- Don’t aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
- Make sure the drainage slots aren’t blocked
- Check the mastic once a year
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Why deal with it now?
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a family home in Epsom, a failed seal around a bath or a frame lets water into places you cannot see, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes anything from an hour or two to a full day, depending on how many frames there are in most cases. For a job in Epsom, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Clear the area around the work
- On commercial sites, let us know about site rules
- Let us know about earlier repairs to the joints

Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Different surfaces, different methods
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Windows and doors in Epsom
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Fitznells Manor (about 1.3 miles north-east) nearby, there’s older building stock in the area around Epsom as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near St. Barnabas Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Epsom station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
