DIY versus a professional finish
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.
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.
How we handle window mastic in Latimer
Around Latimer we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on composite doors, timber windows & doors and window sills, and common reasons people get in touch are untidy mastic left by window fitters and gaps between the frame and the inside reveal.
Somewhere as small as Latimer, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, whatever its size.

When to call us in Latimer
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
It’s worth asking for a quote if you see:
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- A bead that doesn’t match the frame
For an older house near a landmark such as Church of St Mary Magdalene, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Is the old sealant removed completely?
- How hidden problems are handled
- How the joint is cleaned and prepared
- What product goes in the joint
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Rotten timber, which needs a joiner first
- Damp problems in the wall away from the window
- Condensation trapped between the panes
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

Latimer homes and the weather
With historic houses such as Chenies Manor House (about 1.1 miles south-east) nearby, there’s older building stock in the area around Latimer as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Chalfont & Latimer station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Little Chalfont Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.

Advice
Why act early in Latimer
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Around Latimer, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
