Why act early in Stratfield Saye
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Around Stratfield Saye, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

What else we do in Stratfield Saye
Different surfaces, different methods
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. We use a neutral-cure product.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
How it works
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere like Stratfield Saye needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Related advice
Common problems we fix in Stratfield Saye
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Keep an eye out for these signs:
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
Rented homes near Mortimer station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What affects the cost of window mastic
You’ll get a clear quote before any work starts. It takes into account:
- The old material and how stubborn it is
- The number of rooms or windows
- Which sealant suits the joint
- Access and height
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.
Helping us quote
When you call or email, these details help:
- Whether it’s a home or a business
- The problem you’ve noticed
- Photos by email, if that is easy
- Whether it has been sealed before
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job and send photos if you have them.
How to look after the new joints
So the new joints stay in good condition:
- Use gentle cleaners on frames and sealant
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
- Keep solvents and bleach off the sealant
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’re 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 does not work out, we can still put it right.

Window mastic in Stratfield Saye: local notes
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. Historic houses like Stratfield Saye House (about 1.1 miles east) are a reminder that the area around Stratfield Saye has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St. Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
