About our window mastic in Dippenhall
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on composite doors, patio & French doors and timber windows & doors, and common reasons people get in touch are water coming in at the bottom corners of a door and draughty joints inside around the window.
Around Dippenhall, 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.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Why it’s worth doing now in Dippenhall
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Dippenhall, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Your questions about window mastic in Dippenhall
Is Dippenhall in your area for window mastic?
Yes, Dippenhall is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.
Do you work for landlords with property near Farnham station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
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 is a job for a joiner.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that is what we find.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Wash the frames with mild soapy water
- Ventilate rooms so frames do not stay wet inside
- Keep solvents and bleach off the sealant
- Keep drainage slots and sill grooves clear
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Dippenhall homes and the weather
Historic houses like Farnham Castle (about 1.4 miles east) are a reminder that the area around Dippenhall 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Farnham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Potters Gate CofE Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Related advice
Common problems we fix in Dippenhall
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That’s what backing rod is for.
These are the problems we are asked about most:
- Water coming in at the bottom corners of a door
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
- Black, perished sealant on frames
Homes close to St Francis include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing
- How the colour is chosen
- Is the old sealant removed completely?
