Sand mastic for homes and businesses in Chuck Hatch

Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on brick reveals, sash and case windows and timber door frames, and people most often call us about silicone on a period window that looks wrong and mastic round period door frames that has failed.

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

Every job comes with a one-year guarantee.

How we quote for sand mastic

Jobs vary more than people expect. The main factors:

  • The old material and how stubborn it is
  • How much there is to do
  • Whether the work is at height
  • How many areas need sealing

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

What we need to know

You don’t need to know the technical terms. It helps if you can tell us:

  • How many joints, rooms or windows are involved
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel

For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. We will send you a clear quote before any work starts.

Can you do several jobs on one visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

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

In most cases. We remove the silicone and clean the joint, then point it with sand mastic.

Are you insured?

Yes, we’re fully insured for every job we do.

Should I try DIY first?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

Can I do it myself?

If you are set on DIY, put the effort into 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.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

How the visit works

Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. Somewhere like Chuck Hatch needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We check the window surrounds and agree which joints need renewing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic is not too thick.
  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 parking restrictions
  • For indoor joints, keep the area dry beforehand if you can
  • Keep pets and children clear of the area while we work

What sealant work can’t fix

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

  • Planning or listed building consent (your local planning authority decides)
  • Sashes that rattle, stick or won’t open
  • Broken panes

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Joints and surfaces we work on

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

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Plan mastic work ahead of painting
  • Get any rot dealt with first
  • Avoid patching sand mastic with silicone
  • Check the mastic when you check the paintwork

Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.

Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

How the job changes by surface

Period and listed homes

A traditional finish suits a period property, and sand mastic is one of them.

Sash and case windows

A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.

What happens if it’s left?

An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Chuck Hatch can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
