What affects the cost of sand mastic

We quote each job individually. These are the things that affect it:

  • Any mould that needs treating
  • The number of rooms or windows
  • When we can work, for business premises
  • The amount of work

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • The rough size of the job
  • Access, such as stairs, a lift or height
  • Whether it has been sealed before
  • The address or postcode of the job

We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job.

Sand mastic in Stubbington, done properly

Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you are dealing with window mastic to renew ahead of painting and old cement repairs round a window that have failed, we can put it right, whatever the surface.

Homes around Stubbington range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.

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

What sand mastic looks like in Stubbington

Stubbington is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Letting a property close to Fareham station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Crofton Anne Dale Junior School? Then the mastic around its windows and doors needs looking after like any other building’s.

The process

There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a single window, longer for several, including the tidy-up. In a smaller place like Stubbington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children

When to call us in Stubbington

Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.

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

  • Mastic worn away on windows facing the weather
  • Patchy fillers round a sash window
  • Silicone on a period window that looks wrong
  • Draughty sash windows at the surround

If you live in an older home near Holy Rood Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

  • Whether they seal over old material or remove it

FAQs for Stubbington

Does living near the coast affect sand mastic in Stubbington?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

I let a flat near Fareham station. Can you help?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

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.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator.

Where are you based?

We’re based in Crawley, and we cover South East England, London and all of Scotland.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

Are you insured?

Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Looking after it afterwards

After the cure time, these simple habits help:

  • Plan mastic work ahead of painting
  • Check with your local planning authority if your home is listed
  • Have rotten timber repaired before new mastic goes in
  • Avoid heavy scraping on the mastic joint

Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.

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

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. Around Stubbington, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

Doing several joints on one visit is usually more efficient than separate visits. We’ll give you a clear price for the lot.
