About window mastic in Oxfordshire

From a single sill to a whole house of windows, the work is priced before anything is done. To get one, phone 0345 464 0079 or drop us an email with the number of frames and any access details. We work on patio & French doors, timber windows & doors and window sills, and common reasons people get in touch are gaps left after new windows were fitted and mastic that’s falling out in pieces.

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house.

First we look at every frame and agree the list.
We remove the old mastic and clean the frame and the wall.
Deep gaps are filled with backing rod to set the depth.
A flexible, weatherproof sealant is applied in a colour to suit the frame.
Every joint is checked before we leave.

How we quote

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Windows and doors across Oxfordshire

In Oxfordshire, window mastic work takes in houses, flats, conservatories and commercial glazing, in Oxford, Banbury and Didcot 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. For any job in Oxfordshire, joints are cleaned back properly before anything new goes in.

Oxford: Managing a site like East Oxford Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Oxford station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

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 that we can handle for you.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Leave it or put it right?

A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint.

When something else is needed

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

Faulty window hardware
Rotten timber, which needs a joiner first
Damp coming through the wall itself rather than the frame joint

How to look after the new joints

After the cure time, these simple habits help:

Use gentle cleaners on frames and sealant
Keep jet washers away from the mastic
Air rooms to keep condensation down around windows
Repaint timber before it’s bare

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or drop us an email.

On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

Different surfaces, different methods

Aluminium frames

Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.

Window sills

The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.

Your questions about window mastic in Oxfordshire

Is the new sealant paintable?

Silicone generally will not take paint. Let us know beforehand, and we’ll use a paintable product where it suits.

Where is Mr Mastic based?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.

What should I tell you?

Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.

Will new mastic stop draughts?

Yes, where the draught is at the frame edge. We check where the draught is before any work starts.

Do you cover Oxfordshire?

We do. Our applicators work in Oxfordshire, and the service is the same as everywhere else.
