Window mastic in Frindsbury from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Window mastic in Frindsbury, done properly
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you’re dealing with rushed sealant from a window installation and mastic that’s falling out in pieces, we can help.
In a smaller place like Frindsbury, some walls face open ground and catch the full force of the weather. That is hard on the mastic around frames and sills.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

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
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
How it works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we explain the cure time before we leave. A visit to Frindsbury is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before

What happens if it’s left?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. Around Frindsbury, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Domestic, commercial and hotel work

Window mastic in Frindsbury: local notes
Frindsbury is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Strood station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like English Martyrs' Catholic Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
Frindsbury is about 1 mile north-east of Rochester, in Medway.

Signs you need window mastic in Frindsbury
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.
The most common problems we see are:
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
- Mastic that’s falling out in pieces
If you live in an older home near All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Frindsbury: your questions answered
Can you help a landlord with a rental near Strood station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Frindsbury?
Yes, Frindsbury is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we are fully insured.
Are you fully insured?
Yes, we are fully insured for every job we do.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
