Sand mastic near Fyfield

Sand mastic for homes and businesses in Fyfield

We work across Fyfield renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have mastic round period door frames that has failed and wind and rain getting in round a sash window, we can put it right, whatever the surface.

Mastic can only go onto a dry, clean joint, so window work in Fyfield is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Why act early in Fyfield

A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a small place like Fyfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Why us?

  • Over 20 years’ experience
  • Approved under the ARBOMaster scheme
  • We leave the area clean and tidy
  • A 12-month guarantee on all work

Your questions about sand mastic in Fyfield

Do you cover Fyfield for sand mastic?

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

Is Fyfield within the area you cover?

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

Will there be a smell?

Some sealants have a smell while they cure. Opening a window helps.

How long will you be here?

A typical job takes a few hours for a single window, longer for several, including preparation and clearing up. Your quote will say how long we expect yours to take.

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Will it make a mess?

We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.

Do you guarantee sand mastic work?

All our work has a one-year guarantee.

Can you match the sealant colour?

Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.

Frames and glazing around Fyfield

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.

For an older house near a landmark such as Church of St Nicholas, the joint between an old wall and a newer frame is normally the first place rain gets in.

What the job involves on each surface

Brick reveals

An open joint at a brick reveal lets weather in. New mastic seals the gap.

Timber door frames

Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.

Looking after it afterwards

After the cure time, these simple habits help:

  • Inspect the joints round the windows every year or so
  • Leave the new mastic unpainted
  • Avoid patching sand mastic with silicone
  • Get any rot dealt with first

Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.

Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.

Common problems we fix in Fyfield

Timber frames move with the seasons. The movement cracks the mastic little by little.

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

  • Tired mastic found when preparing windows for paint
  • Cracked mastic round a front door frame
  • Weathered mastic on the most exposed windows
  • A silicone bead on a sash window that spoils the look

If you look after a building such as The Ongar Academy, the mastic around its windows and doors needs looking after like any other building’s.

What affects the cost of sand mastic

There’s no set price list, because jobs vary so much. The quote depends on:

  • Mould in or behind the old joints
  • Working hours on commercial sites
  • The size of the job
  • Which sealant suits the joint

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

Photos help, but a description is a good start. Try to tell us:

  • Photos by email, if that is easy
  • The address or postcode of the job
  • If someone has resealed it before
  • What’s wrong with the joints now

Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details, and pictures are welcome.

What we cannot put right

To be straight with you, there are a few things sealant won’t fix:

  • Cracked or broken glass
  • Sash cords, weights and draught-proofing of the sashes
  • Damaged stone surrounds

If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.

Surfaces we seal

  • Period & listed homes
  • Brick reveals
  • Sash and case windows
  • Timber door frames
  • Tenement windows
  • Stone surrounds

How the visit works

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a single window, longer for several. Somewhere as small as Fyfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check the window surrounds and agree which joints need renewing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Deep voids are packed so the mastic is the right thickness.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. We dress the surface so it sits neatly against the masonry.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Keep pets and children clear of the area while we work
  • Let us know about parking restrictions
