About window mastic in Buckinghamshire

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’ll tell you. Typical jobs include draughts coming in around windows and doors and draughty joints inside around the window, on timber windows & doors, composite doors and aluminium frames.

Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from an hour or two to a full day, depending on how many frames there are.

First, we go round the frames with you and agree the list.
We remove the old mastic and clean the frame edge and wall.
Where the gap is deep, backing rod goes in first.
A flexible exterior sealant is applied in a colour to suit the frame.
Every joint is tooled smooth and checked before we leave.

Window mastic across Buckinghamshire: local notes

Our window mastic work across Buckinghamshire covers homes, flats and businesses, in Aylesbury, High Wycombe and Chesham and well beyond. Outside sealant needs a dry, clean joint, so the work is planned around the weather.

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Whatever the job in Buckinghamshire, surfaces are cleaned back properly before new sealant goes in.

Aylesbury: Rented homes near Aylesbury station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as Buckinghamshire UTC, the mastic around its windows and doors needs looking after like any other building’s.

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Letting agents often deal with us directly. Tell us the address, the job and how access works.

Leave it or put it right?

A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint.

Questions to ask before booking

What guarantee comes with the work
Whether they seal over old material or remove it
What product goes in the joint
How much experience the applicator has

When it isn’t the sealant

Before booking, it’s worth knowing the limits too:

Damp problems in the wall away from the window
A sash or casement that will not close properly
Worn gaskets, brush seals or a door that has dropped

Aftercare tips

A little care helps the new joints last. Our advice:

Avoid blasting the frames with a pressure washer
Avoid harsh chemicals near the mastic
Keep timber frames painted
Keep paint off silicone joints

Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.

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.

Common problems we fix in Buckinghamshire

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.

These are the problems we’re asked about most:

Mastic that has split away from the wall
Gaps left after new windows were fitted
Water coming in at the bottom corners of a door
Cold air getting in at the frame edge

Questions from Buckinghamshire

Do you cover Buckinghamshire?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland.

Are you ARBOMaster approved?

Yes. We are an ARBOMaster approved applicator.

Where do you work from?

We’re based in Crawley, and we work across South East England, London and Scotland.

Will new mastic stop draughts?

In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.

Can you reach windows above the ground floor?

Yes, in most cases. We plan safe access before the job.

Does the work come with a guarantee?

Yes. Every job comes with our 12-month guarantee, and we are fully insured.

What should I tell you?

Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
