About our window mastic in Charleshill
Around Charleshill we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on uPVC windows, patio & French doors and timber windows & doors, and people most often call us about gaps between the frame and the inside reveal and cracked or shrunken mastic around the frame.
Mastic can only go onto a dry, clean joint, so window work in Charleshill is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a one-year guarantee.

How the job changes by surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.

The price is agreed before any work begins. It takes into account:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Access and height
- Working hours on commercial sites

What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- Pictures of the joints, sent by email

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Common problems we fix in Charleshill
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Most people get in touch when they notice one of these:
- Whistling draughts around closed windows
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
For landlords with property near Farnham station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- Whether you can choose the colour
- How the joint is cleaned and prepared
- What happens if the job turns out different
- Whether the sealant suits the joint
How it works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job usually takes a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. In a small place like Charleshill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Window mastic in Charleshill: local notes
Historic houses like Farnham Castle (about 3.8 miles north-west) are a reminder that the area around Charleshill 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Waverley Abbey CofE Junior School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St James include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Charleshill is about 3 miles south-east of Farnham, in Surrey. Anywhere in GU10, we cover window mastic for homes and businesses. Charleshill is one of 395 towns and villages in Surrey we cover. You can also see our page for Reading, about 21 miles away.
We cover every part of GU10 for window mastic and the streets around it. Whether your property is on Farnham Road and Whitmead Road or a nearby road, our applicators can take on the job. Charleshill is on the B3001, which makes it straightforward to reach. Close by, we work in Tilford (1 mile west), Elstead (1 mile south-east), Tilford Common (2 miles south-west), Tilford Reeds (2 miles west) and Rushmoor (3 miles south-west). Within a short drive, we also cover Guildford (8 miles north-east), Woking (11 miles north-east), Camberley (10 miles north), Farnham (3 miles north-west), Frimley (8 miles north) and Haslemere (7 miles south).
Local landmarks in Charleshill
Around Charleshill, our work takes us to homes and buildings near The Donkey pub and Thundry Meadows, among other places. For rail, the closest station is Farnham station, about 3.2 miles north-west of the centre. Nearby you’ll also find Museum of Farnham (3.7 miles north-west) and Milford Hospital (4.6 miles east). The countryside around Charleshill includes Runfold Wood and Upper Lake.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Charleshill
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we’ll tell you. Where a wall is exposed, as many are in small places like Charleshill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Why book with us
- Sealant colour chosen to suit
- Colour agreed with you before work begins
- ARBOMaster approved applicator
- Full insurance on every job
What sealant work cannot fix
We will always be straight with you, so here’s what new sealant will not do:
- A sash or casement that won’t close properly
- A failed sealed unit that has misted up
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
What we seal
