Window mastic in Southampton: how it works

Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We are often asked to deal with whistling draughts around closed windows and black, perished sealant on frames, on composite doors, uPVC windows and aluminium frames.

We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a few frames, or a day or more for a whole house.

We check how each frame can be reached safely.
All the failed sealant is cut away.
Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
Backing rod fills deep voids and the sealant goes in on top.
We tool the joint so water runs off, then clear up.

How we quote

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Window mastic across Southampton: local notes

Homes across Southampton range from period properties with timber or sash windows to new builds with uPVC. Exposed walls are where window sealant usually fails first, wherever they are in Southampton.

Hard water across most of the South East leaves limescale on sealant, grout and fittings. For any job in Southampton, joints are cleaned back properly before anything new goes in. Southampton includes coastal places, where outside joints face more wind, rain and salt than they would inland. Joints on seaward walls tend to fail first.

Southampton: For landlords with property near St Denys station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Bevois Town Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

When it isn’t the sealant

New sealant cannot fix everything, and we’ll tell you before we start. It will not solve:

A sash or casement that will not close properly
Damp coming through the wall itself rather than the frame joint
A frame that has rotted at the joint

Surface by surface

Window sills

Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.

Patio & French doors

The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.

Why act early?

Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you.

What we are called out for in Southampton

Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.

These are the problems we are asked about most:

Water coming in at the bottom corners of a door
Hard, cracked sealant around windows
Leaking joints at the ends of sills
White mastic on grey or black frames

What affects the quote in Southampton

Call for a quick quote. The main things that affect it are:

Whether old sealant or filler has to be cut out
The size of the job
Which sealant suits the joint
How many areas need sealing

The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

What we need to know

What to tell us when you ask for a quote:

Any access issues, like height or stairs
Pictures of the joints, sent by email
Where the property is
Whether it’s a home or a business

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Southampton: your questions answered

Where are you based?

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status, and we are fully insured.

Can landlords and businesses book you?

Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.

What do you need from me for a quote?

The location, the problem and the rough size of the job. If you can, email a few pictures.

How many windows can you do in a day?

The work takes a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
