Thorington Street homes and the weather
With historic houses such as Castle House (about 3.7 miles south-east) nearby, there’s older building stock in the area around Thorington Street as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Castle House, about 3.7 miles south-east, is one of the historic houses in the wider area around Thorington Street. Around Thorington Street, as everywhere, window mastic is only as good as the preparation behind it.

About our window mastic in Thorington Street
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. Common call-outs are for cracked or shrunken mastic around the frame and damp patches on the reveal after heavy rain, across patio & French doors, timber windows & doors and window sills.
Around Thorington Street, 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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Thorington Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job. Somewhere as small as Thorington Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are set on DIY, put the effort into 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.
When it is not the sealant
It helps to know what we can’t do:
- Penetrating damp from a failed cavity tray or render
- A sash or casement that will not close properly
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
What we seal

- Window sills

Common questions in Thorington Street
Is there a guarantee on window mastic in Thorington Street?
All our work, in Thorington Street and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will you come out to Thorington Street?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can landlords and businesses book you?
Yes, regularly. Several properties can be quoted together, and between tenancies is a good time for the work.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Is the new sealant paintable?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
