Trusted window mastic in Loose

Loose: your questions answered

Will you come out to Loose?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you work for landlords with property near East Farleigh station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Can new sealant go over the old?

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

Can you do upstairs windows?

Normally, yes. Access is planned before work begins, so mention the height and anything in the way.

Can resealing stop a draught around my window?

In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.

How many windows can you do in a day?

The work takes most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.

Can you work on commercial sites?

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

Can you get sealant to suit coloured frames?

Usually, yes. Tell us the frame colour when you get in touch and we will match it as closely as we can.

Window mastic for homes and businesses in Loose

Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on aluminium frames, window sills and timber windows & doors, and common reasons people get in touch are gaps left after new windows were fitted and a bead that doesn’t match the frame.

In a village or hamlet like Loose, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

A one-year guarantee comes as standard, so you’re covered after we’ve gone.

How it works

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a morning for a couple of windows and a door. For a village or hamlet like Loose, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away.
  3. The surfaces are cleaned and left dry.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • For business premises, tell us about site rules or sign-in
  • Plan for the work area to be out of bounds to pets and children

Keeping the joints in good condition

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

  • Ventilate rooms so frames don’t stay wet inside
  • Look round the frames every year or so
  • Clean frames with a soft cloth and soapy water
  • Don’t use solvent cleaners on the joint

Silicone can’t generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.

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.

Why act early in Loose

Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we’ll tell you. In a small place like Loose, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

How we quote for window mastic

We quote each job individually. These are the things that affect it:

  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating
  • The size of the job
  • The number of rooms or windows

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Helping us quote

To make quoting easier, please include:

  • Where the job is, and your postcode
  • The type of property
  • Any access issues, like height or stairs
  • The rough size of the job

Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Common problems we fix in Loose

Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.

It’s worth asking for a quote if you see:

  • Old mastic that has gone black or come away
  • Mastic that has split away from the wall
  • Rain getting in at the frame or under the sill
  • Gaps where the sill meets the wall

If you let a flat or house near East Farleigh station, renewing tired window mastic between tenants heads off draught and damp complaints.

Comparing quotes

  • What insurance they hold
  • Whether the sealant suits the joint
  • Which colour the sealant will be
  • Whether all the old sealant comes out first

Choosing a sealant specialist

For landlords and businesses

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.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Window mastic in Loose: local notes

With historic houses such as Stoneacre (about 2.8 miles east) nearby, there’s older building stock in the area around Loose as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you live in an older home near Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Loose Primary School, its window and door frames need their mastic kept sound, just like a home’s.
