How we handle window mastic in Minster
Homes in Minster have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include old mastic that has gone black or come away and cold air getting in at the frame edge, on aluminium frames, uPVC windows and patio & French doors.
In a town like Minster, older houses sit alongside newer estates, with windows of every age. In every case, the joint between frame and wall is what keeps water out.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What we are called out for in Minster
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Any of these means the joints need attention:
- Gaps left after new windows were fitted
- Mastic that has split away from the wall
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
Letting a property close to Queenborough station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Minster questions
Is window mastic in a coastal place like Minster any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Queenborough station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
Are you fully insured?
Yes. We are fully insured, and we have been doing sealant work for more than 20 years.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
What we can’t put right
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant will not put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A sash or casement that won’t close properly
- Soft or decayed wood in the frame
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a morning for a couple of windows and a door. Parking in a town like Minster is usually straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, 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.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in

What the job involves on each surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
Window mastic in Minster: local notes
Minster is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Thistle Hill Academy? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around The Abbey Church Of St Mary And St Sexburga, the joint between an old wall and a newer frame is usually the first place rain gets in.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Landlord and commercial work in Minster
If you manage several properties in or around Minster, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and photos by email help.
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Keeping the joints in good condition
Looking after new joints is easy:
- Don’t aim a pressure washer at the joints
- Check the mastic once a year
- Keep solvents and bleach off the sealant
- Clear any debris from frame drain holes
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
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.
