Window mastic in Tatling End
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have water coming in at the bottom corners of a door and rushed sealant from a window installation, we can help, on composite doors, aluminium frames and window sills alike.
Somewhere as small as Tatling End, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a one-year guarantee.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Ventilate rooms so frames do not stay wet inside
- Wash the frames with mild soapy water
- Keep solvents and bleach off the sealant
- Keep paint off silicone joints
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Tatling End questions
I let a flat near Denham Golf Club station. Can you help?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Tatling End?
Yes, Tatling End is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
What does window mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Should I try DIY first?
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.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Signs you need window mastic in Tatling End
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
These are the problems we are asked about most:
- Leaking joints at the ends of sills
- Cracked internal joints between frame and plaster
- Damp patches on the reveal after heavy rain
- A bead that does not match the frame
For landlords with property near Denham Golf Club station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. In a small place like Tatling End, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- 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.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare

Why deal with it now?
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Around Tatling End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we’ll talk you through it.

Windows and doors in Tatling End
With historic houses such as Ickenham Hall (about 4 miles east) nearby, there’s older building stock in the area around Tatling End 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like The Gerrards Cross CofE School? Then the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St James Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right 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.
