About our window mastic in Temple Hill
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, call 0345 464 0079 or email us with the number of frames and any access details. If you have black, perished sealant on frames and rain getting in at the frame or under the sill, we can put it right, on window sills, patio & French doors and uPVC windows alike.
Many houses in smaller places like Temple Hill have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
A one-year guarantee comes as standard, so you are covered after we have gone.

What happens if it’s left?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In an older home around Temple Hill, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a handful of frames, longer for a whole house, including the tidy-up. Parking around Temple Hill is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

Frames and glazing around Temple Hill
With historic houses such as Hall Place and Gardens (about 2.8 miles west) nearby, there’s older building stock in the area around Temple Hill 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. 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.
Managing a site like Temple Hill Primary Academy? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to St Edmunds Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Dartford station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
How much does window mastic cost in Temple Hill?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
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 do upstairs windows?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Can you do the inside joint as well?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.

What else we do in Temple Hill
Looking after it afterwards
After the cure time, these simple habits help:
- Repaint timber before it’s bare
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots are not blocked
- Do not aim a pressure washer at the joints
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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.
