Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Compton homes and the weather
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. With historic houses such as Farnham Castle (about 1.8 miles west) nearby, there’s older building stock in the area around Compton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like South Farnham School? Then its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Farnham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Is the new sealant paintable?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
I’m a tenant. Can you help?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Worn gaskets, brush seals or a door that has dropped
- A frame that has rotted at the joint
- Condensation trapped between the panes
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Where we work in Compton
- uPVC windows
- Timber windows & doors
- Patio & French doors
- Composite doors
- Window sills
- Aluminium frames
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep jet washers away from the mastic
- Paint up to the joint, not over it
- Repaint timber before it’s bare
- Keep solvents and bleach off the sealant
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or email us.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
How the visit works
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. Somewhere like Compton needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- 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.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Let us know about parking restrictions

Advice
Common problems we fix in Compton
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Look out for any of the following:
- Old mastic that has gone black or come away
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
If you live in an older home near St Marys Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- How hidden problems are handled
- Whether all the old sealant comes out first
- Whether you can choose the colour
- The length of the guarantee
How the job changes by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that’s a job for a joiner.
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
