Just ring 0345 464 0079 or email us and tell us how many frames there are and how they’re reached for window mastic in Henley Street. We’re often asked to deal with cracked sealant at the sill ends and mastic that’s falling out in pieces, across patio & French doors, uPVC windows and composite doors.

Window mastic in Henley Street: local notes
With historic houses such as Cobham College (about 0.8 miles north) nearby, there’s older building stock in the area around Henley Street 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. 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.
Schools such as Cobham Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Parish Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Sole Street station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Quotes for window mastic in Henley Street
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- The size of the job
- The product the joint needs
- How easy the joints are to reach
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Helping us quote
To make quoting easier, please include:
- Whether it’s a home or a business
- Where the job is, and your postcode
- The problem you’ve noticed
- How many joints, rooms or windows are involved
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
Should I try it myself first?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Advice
Why act early in Henley Street
Failed mastic is not a reason to replace sound 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 will say so. Older cottages and farmhouses around Henley Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

When it is not the sealant
It helps to know what we can’t do too:
- A frame that has rotted at the joint
- Faulty window hardware
- A failed sealed unit that has misted up
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
What we seal
- Aluminium frames
- Timber windows & doors
- Window sills
- uPVC windows
- Patio & French doors
- Composite doors
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t aim a pressure washer at the joints
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
- Paint up to the joint, not over it
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
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. Early resealing stops it reaching that point.
