Barcombe Mills: your questions answered

Will you come out to Barcombe Mills?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you do window mastic in Barcombe Mills?

Yes, Barcombe Mills is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Are you fully insured?

Yes. We’re fully insured.

Do you work for landlords and businesses?

Yes. We work for householders, landlords, letting agents, businesses and hotels across East Sussex.

How long should I leave it?

That depends on the sealant used, so follow the cure time we give you.

Can I add another job to the visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Can resealing stop a draught around my window?

Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.

Window mastic in Barcombe Mills, done properly

A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. We’re often asked to deal with water coming in at the bottom corners of a door and gaps left after new windows were fitted, on aluminium frames, composite doors and window sills.

Mastic can only go onto a dry, clean joint, so window work in Barcombe Mills is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

We stand behind the work with a one-year guarantee.

What we can’t put right

We’ll always be straight with you, so here’s what new sealant will not do:

  • Faulty window hardware
  • Penetrating damp from a failed cavity tray or render
  • A failed sealed unit that has misted up

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.

What we seal

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

Common problems we fix in Barcombe Mills

On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.

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

  • Gaps between the frame and the inside reveal
  • Cracked sealant at the sill ends
  • Untidy mastic left by window fitters
  • Water coming in at the bottom corners of a door

If you live in an older home near The Parish Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.

Questions to ask before you book

  • What guarantee comes with the work
  • Whether they seal over old material or remove it
  • How the joint is cleaned and prepared
  • Whether you can choose the colour

10 questions to ask before booking

Why deal with it now?

Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Barcombe Mills, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Why us?

  • Approved under the ARBOMaster scheme
  • Colour agreed with you before work begins
  • Domestic, commercial and hotel work
  • Any old sealant cut out fully, not covered over

Window mastic in Barcombe Mills: local notes

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. Historic houses like Glyndebourne (about 3 miles south-east) are a reminder that the area around Barcombe Mills has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

For landlords with property near Cooksbridge station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Barcombe Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

How it works

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a morning for a couple of windows and a door. In a small place like Barcombe Mills, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. Deep gaps get closed-cell backing rod to set the depth.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. Every joint is tooled smooth and checked before we leave.

Before we arrive

  • Mention any tricky access
  • Move anything stored near the joints
  • Mention any parking rules near the property

Related advice

Should I try it myself first?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

For landlords and businesses

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

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

Surface by surface

Composite doors

Front doors take the weather head on. We pay most attention there.

uPVC windows

Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
