Tyburn homes and the weather
With historic houses such as Handel Hendrix House (about 0.8 miles east) nearby, there’s older building stock in the area around Tyburn 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. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
For site and facilities teams at buildings such as Hampden Gurney CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near London Paddington station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How we handle window mastic in Tyburn
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We are often asked to deal with rain getting in at the frame or under the sill and rushed sealant from a window installation, on window sills, aluminium frames and uPVC windows.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Tyburn.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

When to call us in Tyburn
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Look out for any of the following:
- Whistling draughts around closed windows
- Hard, cracked sealant around windows
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
Homes close to Church of the Annunciation include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

- When the joint can take water or movement
- What insurance they hold

Common questions in Tyburn
Is Tyburn in your area for window mastic?
Yes. Our work covers London and the South East, and Tyburn is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Do you work for landlords with property near London Paddington station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
How do I get a quote for window mastic in Tyburn?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before work begins.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep paint off silicone joints
- Keep jet washers away from the mastic
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
How we quote for window mastic
There’s no set price list. The quote depends on:
- The type of sealant required
- Mould in or behind the old joints
- The number and length of the joints
- How many rooms, windows or areas are involved

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- A failed sealed unit that has misted up
- A sash or casement that won’t close properly
- A frame that has rotted at the joint
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
