Window mastic in Shalmsford Street
Homes in Shalmsford Street have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on aluminium frames, uPVC windows and composite doors, and people most often call us about leaking joints at the ends of sills and cracked or shrunken mastic around the frame.
In smaller places like Shalmsford Street, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How the job changes by surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the new bead is laid against the frame and the wall.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
Looking after new joints is easy:
- Keep paint off silicone joints
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
- Avoid harsh chemicals near the mastic
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Shalmsford Street: your questions answered
Do you work for landlords with property near Chartham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Shalmsford Street?
Yes. Shalmsford Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where is Mr Mastic based?
We work from Crawley. We cover Shalmsford Street and the rest of Kent.
What information do you need?
Let us know what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
How much does window mastic cost in Shalmsford Street?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or drop us an email with a short description of the job.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Frames and glazing around Shalmsford Street
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.
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Chartham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Chartham Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Why deal with it now?
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In an older home around Shalmsford Street, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint usually makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What else we do in Shalmsford Street
The process
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames for a typical job. Parking around Shalmsford Street is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
