Our window mastic service in Kent

From a single sill to a whole house of windows, the work is priced before anything is done. Just ring 0345 464 0079 or email us and tell us how many frames there are and how they’re reached. Typical jobs include black, perished sealant on frames and mastic that has split away from the wall, on composite doors, uPVC windows and timber windows & doors.

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 work begins. The work usually takes a morning for a couple of windows and a door.

We check how each frame can be reached safely.
Old, cracked mastic is removed completely.
The surfaces are cleaned and left dry.
Deep voids are backed, then the sealant is gunned in.
The joint is shaped to shed water and the area tidied.

Window mastic across Kent: local notes

Kent has everything from older homes with timber frames to newer ones with uPVC. Walls facing the weather take the most punishment, wherever they are in Kent.

London and the South East have homes from every era, from period terraces to post-war new towns and new estates. Each needs the right sealant for its age and materials, wherever it is in Kent. Parts of Kent are on or near the coast, where wind-driven rain and, closer to the shore, salt air are hard on outside sealant. Walls facing the sea are generally the first to need attention.

Maidstone: Letting a property close to Maidstone West station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like South Borough Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

How the job changes by surface

uPVC windows

Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.

Timber windows & doors

Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.

What sealant work cannot fix

Some problems need a builder, plumber or other trade rather than us:

Rotten timber, which needs a joiner first
A sash or casement that won’t close properly
Damp problems in the wall away from the window

Can I do it myself?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Working hours on commercial sites
Whether the work is at height
The number and length of the joints
How many areas need sealing

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Photos help, but a description is a good start. Please mention:

What the problem is, such as mould, gaps, leaks or cracking
Pictures of the joints, sent by email
Any access issues, like height or stairs
Where the job is, and your postcode

It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or drop us an email.

Landlords and agents in Kent can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Your questions about window mastic in Kent

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Can you do several jobs on one visit?

Of course. Combining jobs makes good use of the visit.

Do you work in Kent?

Yes. We work in Kent, as part of our work across South East England, London and Scotland. For a quote, call 0345 464 0079 or email us.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints.

Does the work come with a guarantee?

Yes. Our one-year guarantee covers every job, inside or out.

What should I tell you?

Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.

Will resealing my frames help with draughts?

Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
