Window & door mastic in St Michaels, Kent
Professional window mastic in and around St Michaels, with every bit of old sealant taken out first.
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
- A bead that doesn’t match the frame
Window mastic for homes and businesses in St Michaels
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Typical jobs include rain getting in at the frame or under the sill and cracked internal joints between frame and plaster, across window sills, uPVC windows and patio & French doors.
Mastic can only go onto a dry, clean joint, so window work in St Michaels is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, you get the same one-year guarantee in St Michaels and across Kent.

What affects the quote in St Michaels
Every job gets its own quote. This is what makes a difference:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- The size of the job
- Whether the work is at height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

FAQs for St Michaels
Is window mastic in St Michaels guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is St Michaels within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do you work on first-floor windows?
Generally, yes. Access is planned before work begins.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in St Michaels.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Common problems we fix in St Michaels
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Signs it’s time to call us include:
- Cracked sealant at the sill ends
- Draughty joints inside around the window
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
Homes close to Church of St Michael include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- Who does the work, and how experienced they are
- Whether VAT is included
- What preparation is included
- Whether the sealant suits the joint
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Make sure the drainage slots are not blocked
- Air rooms to keep condensation down around windows
- Repaint timber before it’s bare
- Keep solvents and bleach off the sealant
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
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.
Landlord and commercial work in St Michaels
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What window mastic looks like in St Michaels
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Smallhythe Place (about 3.3 miles south) nearby, there’s older building stock in the area around St Michaels as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as St Michael's Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

How it works
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a morning for a couple of windows and a door in most cases. In a small place like St Michaels, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- 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
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on

Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a small place like St Michaels, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
