Little Wittenham: your questions answered
Is Little Wittenham in your area for window mastic?
Yes, Little Wittenham is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Little Wittenham?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Do you work for landlords and businesses?
Yes, regularly. Several properties can go on one quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Window mastic for homes and businesses in Little Wittenham
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you are dealing with cold air getting in at the frame edge and draughty joints inside around the window, we can put it right.
Somewhere as small as Little Wittenham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

Do you need window mastic in Little Wittenham?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That’s what backing rod is for.
Look out for any of the following:
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
- White mastic on grey or black frames
- Draughts coming in around windows and doors
Managing a site like Long Wittenham (Church of England) Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- How long the guarantee is
- How the joint is cleaned and prepared
- How long to leave it before use
- What the quote includes, VAT included or not
What happens if it’s left?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a small place like Little Wittenham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Looking after it afterwards
So the new joints stay in good condition:
- Wash the frames with mild soapy water
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
- Avoid blasting the frames with a pressure washer
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
What we do, step by step
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house for a typical job. In a small place like Little Wittenham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- 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.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

What window mastic looks like in Little Wittenham
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Brightwell Manor (about 1.7 miles south-east) nearby, there’s older building stock in the area around Little Wittenham 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’s traditional sand mastic.
Homes close to Church of St Peter 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 Appleford station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
