How we handle window mastic in Upper Eddington
Homes in Upper Eddington have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you’re dealing with cracked sealant at the sill ends and water coming in at the bottom corners of a door, we can help.
Around Upper Eddington, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, large or small.

FAQs for Upper Eddington
Can you do window mastic in Upper Eddington?
Yes. We work across London and the South East, and Upper Eddington is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Can you help a landlord with a rental near Hungerford station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What does window mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can new window sealant be painted?
Not normally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Window mastic in Upper Eddington: 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.
Schools such as Hungerford Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Hungerford Methodist Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Common problems we fix in Upper Eddington
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Keep an eye out for these signs:
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
- Draughty joints inside around the window
- Draughts coming in around windows and doors
Letting a property close to Hungerford station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Around Upper Eddington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Somewhere as small as Upper Eddington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Clear items away from the joints we are working on

How the job changes by surface
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Clear any debris from frame drain holes
- Keep paint and stain on wooden frames in good order
- Clean frames with a soft cloth and soapy water
- Wipe condensation off the frames
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
