How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door. For a village or hamlet like Ockham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions

How we handle window mastic in Ockham
Around Ockham we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Common call-outs are for rain getting in at the frame or under the sill and cold air getting in at the frame edge, on aluminium frames, uPVC windows and patio & French doors.
Around Ockham, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Why act early in Ockham
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Ockham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before work begins.
What you get with us
- Quality sealants from Arbo and Everbuild
- Tidy, careful work
- A sealant colour to suit the surroundings

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Keep drainage slots and sill grooves clear
- Wipe condensation off the frames
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
When to call us in Ockham
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. Backing rod sets the right depth.
Look out for any of the following:
- Hard, cracked sealant around windows
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
- Damp patches on the reveal after heavy rain
For an older house near a landmark such as All Saints' Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Whether you can choose the colour
- How the surfaces are prepared before sealing
- How long to leave it before use
- Who turns up on the day
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Condensation trapped between the panes
- Faulty window hardware
- Penetrating damp from a failed cavity tray or render
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Ockham questions
I let a flat near Horsley station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Ockham?
Yes, Ockham is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What should I tell you?
A short description and the location, with photos by email if possible. We will ask anything else we need to know.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is the new sealant paintable?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Where do you work from?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Frames and glazing around Ockham
With historic houses such as Byfleet Manor (about 2.3 miles north) nearby, there’s older building stock in the area around Ockham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Horsley station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Ripley Court School? Then the mastic around its windows and doors needs looking after like any other building’s.
