Trusted window mastic in Garlinge

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 that is a job for a joiner.

Window sills

Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.

Window mastic in Garlinge

Homes in Garlinge have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you’re dealing with untidy mastic left by window fitters and sealant in the wrong colour for the frame, we can help, on timber windows & doors, uPVC windows and window sills alike.

Many houses in smaller places like Garlinge have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.

Big or small, you get the same 12-month guarantee.

When it isn’t the sealant

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Rotten timber, which needs a joiner first
  • A sash or casement that will not close properly
  • Damp problems in the wall away from the window

If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Surfaces we seal

  • Window sills
  • Aluminium frames
  • Patio & French doors
  • uPVC windows
  • Timber windows & doors
  • Composite doors

Frames and glazing around Garlinge

Garlinge is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

How the visit works

We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are. A visit to Garlinge is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. First, we go round the frames with you and agree the list.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. We tool each bead neatly and check every joint is closed.

How to prepare

  • Tell us about any previous sealing or DIY attempts
  • Mention any leaks or damp you’ve noticed
  • Mention any sign-in or site rules at work premises

Your questions about window mastic in Garlinge

Does the coastal weather in Garlinge affect outside sealant?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Do you cover smaller places like Garlinge?

Yes. Garlinge is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you seal inside as well as outside?

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

Can I add another job to the visit?

Yes. More than one area can be quoted together.

Do you work on first-floor windows?

Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.

Do you remove the old sealant?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Does someone need to be in?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Can you match the sealant to my frames?

Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll use the nearest match.

Common problems we fix in Garlinge

Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.

Look out for these signs:

  • Cold air getting in at the frame edge
  • Cracked sealant at the sill ends
  • Water coming in at the bottom corners of a door
  • Mastic that’s falling out in pieces

For an older house near a landmark such as St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Our hiring checklist

Landlords, agents and businesses in Garlinge

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Why deal with it now?

Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Homes in smaller places like Garlinge can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
