How we handle sand mastic in Lynsted

For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with wind and rain getting in round a sash window and mastic that needs renewing before redecorating, on brick reveals, tenement windows and period & listed homes.

Somewhere as small as Lynsted, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

For landlords and businesses

We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.

What affects the quote in Lynsted

Jobs vary more than people expect. The main factors:

  • How many areas need sealing
  • When we can work, for business premises
  • How easy the joints are to reach
  • The old material and how stubborn it is

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Asking for a quote

When you contact us, these details help:

  • A few pictures by email, if you can
  • Any access issues, like height or stairs
  • The type of property
  • How many joints, rooms or windows are involved

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Why it’s worth doing now in Lynsted

New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Lynsted, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Combining jobs into one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

Honest limits

Before booking, it’s worth knowing the limits too:

  • Rotten sashes, sills or window boxes (a joiner’s job)
  • Crumbling stone or brickwork round the window
  • Whether work needs listed building consent

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Surfaces we seal

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

What happens on the day

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints in most cases. In a small place like Lynsted, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

Getting ready for the visit

  • Tell us if parking is tricky
  • Move anything stored near the joints
  • Mention any sign-in or site rules at work premises

Frames and glazing around Lynsted

With historic houses such as Belmont House and Gardens (about 3.8 miles south-east) nearby, there’s older building stock in the area around Lynsted 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Rented homes near Teynham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to Church of St Peter and St Paul include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

What we are called out for in Lynsted

Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.

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

  • Patchy fillers round a sash window
  • Draughts and rain around sash boxes
  • Open joints round the window box
  • Failed mastic on an exposed elevation

Managing a site like Lynsted and Norton Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

What to look for in a quote

  • Which sealant they’ll use, and why
  • How the joint is cleaned and prepared
  • Who turns up on the day
  • How the colour is chosen

Our hiring checklist

DIY versus a professional finish

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 does not work out, we can still put it right.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
