Sand mastic for Ferring homes and businesses

How we handle sand mastic in Ferring

Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. If you’re dealing with gaps between timber frames and stone or brick and old sand mastic that has cracked, crumbled or fallen out, we can put it right, on sash and case windows, timber door frames and stone surrounds alike.

Houses in smaller places like Ferring can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.

We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Check with your local planning authority if your home is listed
  • Sort the mastic before the decorators arrive
  • Avoid patching sand mastic with silicone
  • Ask a joiner to look at soft timber first

Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.

Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

We also work for property managers and facilities teams in Ferring and across West Sussex. We can quote a run of properties together, and we are fully insured.

Common problems we fix in Ferring

Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.

Keep an eye out for these signs:

  • Crumbling sand mastic round a window
  • Failed mastic on an exposed elevation
  • Cracked mastic round a front door frame
  • Patchy fillers round a sash window

In the older streets around St Andrew's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

10 questions to ask before booking

DIY versus a professional finish

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Ferring questions

Will you come out to Ferring?

Yes, Ferring is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

I let a flat near Goring-By-Sea station. Can you help?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Should I use sand mastic or silicone?

We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

Is the work guaranteed?

Our 12-month guarantee applies on every job.

Where do you work from?

We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Do the sealants smell?

Sometimes, a little. Any smell clears as the sealant cures.

Different surfaces, different methods

Sash and case windows

The mastic round a sash window is on show so we finish it carefully.

Timber door frames

Doors face weather and wear and the mastic can crack early. We rake it out and renew it.

What happens if it’s left?

Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In a smaller place like Ferring, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Ferring homes and the weather

Ferring 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’s 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.

Letting a property close to Goring-By-Sea station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Ferring CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a single window, longer for several. A visit to Ferring is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.
