About our sand mastic in Faversham

Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. We work on sash and case windows, brick reveals and stone surrounds, and people most often call us about gaps between timber frames and stone or brick and window mastic to renew ahead of painting.

Faversham mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.

The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Sand mastic in Faversham: local notes

Faversham is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.

Rented homes near Faversham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St Mary Magdalene, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Ask the planning authority about consent for listed or conservation-area homes
  • Do not run silicone over sand mastic
  • Check the mastic when you check the paintwork
  • Ask a joiner to look at soft timber first

Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.

Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

How the job changes by surface

Period and listed homes

Period homes look their best with traditional materials, and sand mastic is one of them.

Sash and case windows

The mastic round a sash window is on show, so a neat, even finish matters.

When it isn’t the sealant

New sealant can’t fix everything, and we will tell you before we start. Sealant won’t put right:

  • Sashes that need overhauling
  • Decayed frames that need repair
  • Whether work needs listed building consent

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

Joints and surfaces we work on

  • Stone surrounds
  • Brick reveals

Quotes for sand mastic in Faversham

The price is agreed before any work begins. It takes into account:

  • Whether the work is at height
  • Which sealant suits the joint
  • The old material and how stubborn it is
  • Any working-time requirements on site

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Helping us quote

To help us quote quickly, please include:

  • The address or postcode of the job
  • Photos by email, if that is easy
  • The type of property
  • If someone has resealed it before

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

The process

At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. Parking in a town like Faversham is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.

  1. We check the window surrounds and agree which joints need renewing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. Deep voids are packed so the mastic is the right thickness.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. We dress the surface so it sits neatly against the masonry.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints
  • On commercial sites, let us know about site rules

Your questions about sand mastic in Faversham

Can you help a landlord with a rental near Faversham station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Does living near the coast affect sand mastic in Faversham?

Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.

Where do you work from?

Mr Mastic is based in Crawley. Our applicators cover Faversham.

When will the new mastic be hard?

The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.

Do the sealants smell?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Can you replace silicone on a period window with sand mastic?

Yes. We remove the silicone and clean the joint before the sand mastic goes in.

Is it possible to paint over sand mastic?

Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.

How do I get a quote for sand mastic in Faversham?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Signs you need sand mastic in Faversham

Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.

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

  • Gaps round a timber door in stone or brick
  • A silicone bead on a sash window that spoils the look
  • Patchy fillers round a sash window
  • Gaps between timber frames and stone or brick

Schools such as Ethelbert Road Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What your quote should include

  • How the surfaces are prepared before sealing
  • Which colour the sealant will be
  • Whether all the old sealant comes out first
  • How much experience the applicator has
