About window mastic in Hampshire

Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before we start. Just phone 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. Common call-outs are for sealant in the wrong colour for the frame and water coming in at the bottom corners of a door, across aluminium frames, patio & French doors and uPVC windows.

When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take most of a day for a typical house, less for a few frames.

First, we go round the frames with you and agree the list.
The old mastic is cut out and scraped back to clean surfaces.
Deep gaps get closed-cell backing rod to set the depth.
The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
Every joint is tooled smooth and checked before we leave.

Frames and weather across Hampshire

Across Hampshire, from Basingstoke, Winchester and Gosport outwards, frames range from older timber to modern uPVC and aluminium. Each needs the right sealant, and every joint wears out eventually.

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Whatever the job in Hampshire, surfaces are cleaned back properly before new sealant goes in. Hampshire includes coastal places, where outside joints face more wind, rain and salt than they would inland. Walls facing the sea are usually the first to need attention.

Basingstoke: Managing a site like King's Furlong Infant School and Nursery? Then larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Michael's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Landlord and commercial work in Hampshire

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

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

Signs you need window mastic

Sills take more water than any other part of a window, 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.

If you can see any of these, it’s time to have the joints looked at:

Sealant in the wrong colour for the frame
Draughty joints inside around the window
Old mastic that has gone black or come away
Mastic that has split away from the wall

Different surfaces, different methods

Timber windows & doors

Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.

Patio & French doors

Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.

What happens if it’s left?

Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall.

What affects the quote in Hampshire

Some jobs are bigger than they look, and some smaller. What affects the quote:

The product the joint needs
How easy the joints are to reach
Any working-time requirements on site
The number of rooms or windows

What you pay reflects the work, not guesswork. That is why we ask a few questions first.

What to tell us for a quote

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

The type of property
If someone has resealed it before
What’s wrong with the joints now
Access, such as stairs, a lift or height

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Your questions about window mastic in Hampshire

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can you do the inside joint as well?

Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.

Do you work in Hampshire?

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

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint.

Will new mastic stop draughts?

If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.

How long before the joint can be used?

Cure times vary by product and the conditions. We tell you how long to leave it before we go.
