Your questions about window mastic in Green Hailey

Is Green Hailey within the area you cover?

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.

Can you do window mastic in Green Hailey?

Yes, Green Hailey is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Can you do several jobs on one visit?

Yes. More than one area can go on one quote.

Is it OK to seal over old sealant?

No. The old sealant always comes out first.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Do you take out the old sealant first?

Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

About our window mastic in Green Hailey

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have rain getting in at the frame or under the sill and cracked internal joints between frame and plaster, we can put it right, whatever the surface.

Homes in small places like Green Hailey often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

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

Can I do it myself?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Windows and doors in Green Hailey

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For an older house near a landmark such as Church of St Dunstan, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Monks Risborough station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Monks Risborough CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Surface by surface

Aluminium frames

Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.

Composite doors

Front doors take the weather head on. Those corners get the most care.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Make sure the drainage slots aren’t blocked
  • Use gentle cleaners on frames and sealant
  • Keep paint off silicone joints
  • Keep timber frames painted

Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.

A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

How it works

There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of frames, longer for a whole house from start to finish. For a village or hamlet like Green Hailey, 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. Each frame is looked over and we agree which ones need resealing.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. Every joint is tooled smooth and checked before we leave.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before
