Window mastic for homes and businesses in Althorne

Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. Typical jobs include rain getting in at the frame or under the sill and white mastic on grey or black frames, across patio & French doors, window sills and aluminium frames.

In a village or hamlet like Althorne, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

What we are called out for in Althorne

Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.

The problems people usually mention when they call are:

  • White mastic on grey or black frames
  • Black, perished sealant on frames
  • Water coming in at the bottom corners of a door
  • Whistling draughts around closed windows

Letting a property close to Althorne station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Questions to ask before booking

  • How long to leave it before use
  • What preparation is included
  • Which sealant they’ll use, and why
  • What happens if they find a problem under the old sealant

Our hiring checklist

Aftercare tips

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Look round the frames every year or so
  • Make sure the drainage slots aren’t blocked
  • Wash the frames with mild soapy water
  • Keep timber frames painted

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.

Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Leave it or put it right?

The work is quick compared with the damage it prevents: it takes most of a day for a typical house, less for a few frames. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Althorne, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Why choose Mr Mastic in Althorne

  • Neat joints and a tidy finish
  • Full insurance on every job
  • Colour agreed with you before work begins
  • Sanitary silicone with an anti-fungal additive in wet areas

The process

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take most of a day for a typical house, less for a few frames. In a small place like Althorne, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Before we arrive

  • Tell us about any water getting in
  • On commercial sites, let us know about site rules
  • Clear the area around the work

Advice

Windows and doors in Althorne

Althorne is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Homes close to Parish Church of St Andrew include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Althorne

Does living near the coast affect window mastic in Althorne?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Do you cover smaller places like Althorne?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for hotels and businesses?

Yes. Larger jobs can be planned room by room or area by area.

Can landlords and businesses book you?

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

How long will my window job take?

A few frames take a few hours. We confirm the timing with your quote.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and we will quote it together.

Do you work on first-floor windows?

Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.

Can you seal the gap between the frame and the plaster indoors?

Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.

When something else is needed

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • A sash or casement that won’t close properly
  • A frame that has rotted at the joint
  • Penetrating damp from a failed cavity tray or render

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

Where we work in Althorne

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

Can I do it myself?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
