About our window mastic in Wigmore
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. Common call-outs are for rain getting in at the frame or under the sill and cracked internal joints between frame and plaster, across window sills, aluminium frames and patio & French doors.
Houses in smaller places like Wigmore can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.

What else we do in Wigmore
What we do, step by step
At the end, we look at the finished work together. The visit itself generally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. In a smaller place like Wigmore, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Frames and glazing around Wigmore
Wigmore is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Rainham (Kent) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Park Wood Infant School, larger buildings have plenty of frames, and the mastic around each one ages.
Wigmore is about 1 mile south-east of Gillingham, in Medway. Wigmore gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Wigmore is one of 68 places in Medway where we work for window mastic. Our Chelmsford page covers work nearby, about 27 miles away.
All of ME8 is within our area for window mastic, from the main roads to the quietest streets. If you need window mastic at a property on Durham Road, Harvey Road and Arthur Road or a nearby road, our applicators can take on the job. If you’re just outside Wigmore, we cover Park Wood (1 mile south), Hempstead (1 mile west), Twydall (1 mile north), Gillingham (1 mile north-west) and Capstone (2 miles west). Within a short drive, we also cover Chatham (3 miles west), Rochester (5 miles north-west), Strood (6 miles north-west), Luton (3 miles west), Lordswood (3 miles south-west) and Hoo St Werburgh (5 miles north).
What’s near Wigmore
Around Wigmore, our work takes us to homes and buildings near Foxburrow Wood, Howard School and The Railway pub. For rail, the closest station is Rainham (Kent) station, roughly 1 mile north-east of the centre. Other landmarks nearby include Upnor Castle (4.6 miles north-west) and Pentagon Shopping Centre (3.6 miles north-west). The countryside around Wigmore includes Boxley Hills and Bishop Saltings.
Can I do it myself?
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, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Homes in smaller places like Wigmore can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before any work starts.

Questions from Wigmore
Will you come out to Wigmore?
Yes, Wigmore is covered. 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.
Does the coastal weather in Wigmore affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where do you work from?
We work from Crawley. We cover Wigmore and the rest of Medway, along with the rest of our area.
Do you need window mastic in Wigmore?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That is what backing rod is for.
The most common problems we see are:
- Leaking joints at the ends of sills
- Draughty joints inside around the window
- Water coming in at the bottom corners of a door
- Untidy mastic left by window fitters
In the older streets around St Paul's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
Before you book anyone
- What insurance they hold
- Whether they seal over old material or remove it
- When the joint can take water or movement
- Which sealant they’ll use, and why
For landlords and businesses
We also work for property managers and facilities teams in Wigmore and across Medway. We can quote a run of properties together, and we are fully insured.
For anyone letting property in or around Wigmore, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
When something else is needed
We will always be straight with you, so here’s what sealant cannot fix:
- Damp problems in the wall away from the window
- Rotten timber, which needs a joiner first
- Worn gaskets, brush seals or a door that has dropped
