Window mastic for homes and businesses in East Hendred
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have gaps between the frame and the inside reveal and rushed sealant from a window installation, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in East Hendred is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with a one-year guarantee.

FAQs for East Hendred
Can you help a landlord with a rental near Didcot Parkway station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Will you come out to East Hendred?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we are using and why.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do the sealants smell?
Some sealants have a smell while they cure. 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 will talk you through it.
Where is Mr Mastic based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
Can I paint over the new sealant?
Most silicone cannot be painted. Let us know beforehand, and we’ll use a paintable product where it suits.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- The type of sealant required
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- The rough size of the job
- Pictures of the joints, sent by email
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.
For landlords and businesses
If you manage several properties in or around East Hendred, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and photos by email help.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
Leave it or put it right?
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. Around East Hendred, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What you get with us
- We leave the area clean and tidy
- Any old sealant cut out fully, not covered over
- Over 20 years’ experience
- A 12-month guarantee on all work

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Avoid blasting the frames with a pressure washer
- Keep paint off silicone joints
- Ventilate rooms so frames don’t stay wet inside
- Keep paint and stain on wooden frames in good order
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Windows and doors in East Hendred
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.
Homes close to Church of St Augustine of Canterbury include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Didcot Parkway station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like The Hendreds Church of England School? Then the mastic around its windows and doors needs looking after like any other building’s.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as East Hendred, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- 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.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
