In a village or hamlet like Heath End, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

What the job involves on each surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What happens on the day
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work starts. The work normally takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Heath End, 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 how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Keep children and pets away from the work area

Heath End homes and the weather
Historic houses like Farnham Castle (about 1.4 miles south-west) are a reminder that the area around Heath End 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St Mark the Evangelist Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Farnham Heath End School, the mastic around its windows and doors needs looking after like any other building’s.

Common problems we fix in Heath End
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Any of these means the joints need attention:
- Gaps left after new windows were fitted
- Old mastic that has gone black or come away
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
Letting a property close to Aldershot station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Is the work guaranteed?

What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
When is the sealant fully cured?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Landlord and commercial work in Heath End
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
- Paint up to the joint, not over it
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
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.
Why it’s worth doing now in Heath End
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Heath End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
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 we need extra access for height. Your quote takes all of that into account.
