About our window mastic in Stanhope
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We’re often asked to deal with gaps where the sill meets the wall and gaps left after new windows were fitted, across aluminium frames, window sills and composite doors.
In smaller places like Stanhope, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Your questions about window mastic in Stanhope
Do you work for landlords with property near Ashford International station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Can you do window mastic in Stanhope?
Yes. We work across London and the South East, and Stanhope is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
What do you need from me for a quote?
Tell us what needs doing and where. We’ll ask anything else we need to know.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. A visit to Stanhope is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

Advice
Frames and glazing around Stanhope
With historic houses such as Godinton House (about 2.1 miles north-west) nearby, there’s older building stock in the area around Stanhope as well as newer homes. In older buildings, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St. Francis include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Beaver Green 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 Ashford International station, renewing tired window mastic between tenants heads off draught and damp complaints.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first
- A sash or casement that will not close properly
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Do not paint over the silicone
- Avoid blasting the frames with a pressure washer
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
