Moor Street Window Mastic
Problem with your window and door frames in Moor Street? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Cracked internal joints between frame and plaster
- Mastic that has split away from the wall
- Leaking joints at the ends of sills
How we handle window mastic in Moor Street
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We are often asked to deal with whistling draughts around closed windows and cracked internal joints between frame and plaster, across patio & French doors, window sills and aluminium frames.
Outdoor sealant needs dry, clean surfaces, so work on frames around Moor Street is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Why act early in Moor Street
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Moor Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Pictures of the joints, sent by email
- Where the property is
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, call 0345 464 0079 or send us an email.
What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work starts. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Moor Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- 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.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

Frames and glazing around Moor Street
Moor Street is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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.
Managing a site like Leigh Academy Rainham? Then its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Rainham (Kent) station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Moor Street is about 2 miles east of Gillingham, in Medway. We carry out window mastic for homeowners, landlords and businesses in Moor Street, as part of our work across Medway. Moor Street is one of 68 towns and villages in Medway where we work for window mastic. Our Chelmsford page covers work nearby.
Every address in ME8 is within our area for window mastic, from the main roads to the quietest streets.

The countryside around Moor Street includes Bishop Saltings and Detling Hill.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t use solvent cleaners on the joint
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
- Wash the frames with mild soapy water
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.
Moor Street: your questions answered
Does the coastal weather in Moor Street affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Rainham (Kent) station?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you cover Moor Street?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Moor Street.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
How the job changes by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Common problems we fix in Moor Street
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Common reasons people contact us include:
- Leaking joints at the ends of sills
- Rain getting in at the frame or under the sill
- Mastic that’s falling out in pieces
- Gaps between the frame and the inside reveal
If you live in an older home near Church of St Margaret, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
