Window mastic across Essex: what to expect

Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on window sills, uPVC windows and timber windows & doors, and common reasons people get in touch are cracked or shrunken mastic around the frame and cold air getting in at the frame edge.

We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of frames, longer for a whole house.

We check how each frame can be reached safely.
All the failed sealant is cut away.
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.
We tool the joint so water runs off, then clear up.

Window mastic across Essex: local notes

In Essex, window mastic work takes in houses, flats, conservatories and commercial glazing, from Colchester, Chelmsford and Basildon to the quieter places in between. Outside sealant needs a dry, clean joint, so the work is planned around the weather.

London and the South East are among the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across Essex is planned around the weather. In the coastal parts of Essex, the sea-facing side of a building takes the most weather, so they’re often the first to fail. Good preparation and the right sealant help it cope.

Colchester: If you look after a building such as Colchester Sixth Form College, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Colchester Town station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Leave it or put it right?

A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job.

Signs you need window mastic

Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.

Keep an eye out for these signs:

Untidy mastic left by window fitters
Hard, cracked sealant around windows
Cracked sealant at the sill ends
Rain getting in at the frame or under the sill

When it is not the sealant

Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant will not put right:

A frame that has rotted at the joint
Faulty window hardware
A failed sealed unit that has misted up

Quotes for window mastic in Essex

The price is agreed before any work begins. It’s based on:

The size of the job
Whether the work is at height
How many rooms, windows or areas are involved
When we can work, for business premises

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What we need to know

What to tell us when you ask for a quote:

How we’d reach the joints
Where the job is, and your postcode
What the problem is, such as mould, gaps, leaks or cracking
Whether it has been sealed before

There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or send us an email.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

Avoid blasting the frames with a pressure washer
Paint up to the joint, not over it
Avoid harsh chemicals near the mastic
Air rooms to keep condensation down around windows

A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or email us.

Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

Essex: your questions answered

Is the work guaranteed?

Yes. Our 12-month guarantee covers every job, inside or out.

Do the sealants smell?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do you come to Essex?

Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Essex.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Do you do commercial work?

Yes. We can plan bigger jobs in stages.

Is it OK to seal over old sealant?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
