About our window mastic in Hampton
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have damp patches on the reveal after heavy rain and white mastic on grey or black frames, we can help, whatever the surface.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Should I try it myself first?
Too much sealant is as bad as too little. 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: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep paint and stain on wooden frames in good order
- Don’t aim a pressure washer at the joints
- Don’t use solvent cleaners on the joint
- Wipe condensation off the frames
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Your questions about window mastic in Hampton
I let a flat near Hampton station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Can parking be tricky for a visit in Hampton?
Parking in Hampton, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Are you fully insured?
Yes. Full insurance covers our work.
Does the work come with a guarantee?
Yes. Our one-year guarantee covers every job, inside or out.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
How much does window mastic cost in Hampton?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What we cannot put right
To be straight with you, some problems need a different trade:
- A frame that has rotted at the joint
- A sash or casement that won’t close properly
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

What affects the quote in Hampton
Every job gets its own quote. This is what makes a difference:
- Access and height
- When we can work, for business premises
- Mould in or behind the old joints
- How many areas need sealing
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- A few photos by email, if you can
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job and send pictures if you have them.
How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In Hampton, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Frames and glazing around Hampton
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In a converted house or block, who looks after the windows depends on the lease, so check that before you book.
For site and facilities teams at buildings such as Hampton Infant School and Nursery, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Hampton station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to All Saints' Hampton include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
