About our sand mastic in Hordle
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we will advise if you’re redecorating. If you are dealing with failed mastic on an exposed elevation and draughty sash windows at the surround, we can put it right, whatever the surface.
Houses in smaller places like Hordle 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.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Do you need sand mastic in Hordle?
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
Any of these means the joints need attention:
- Gaps where the frame meets the masonry
- Cracked mastic round a front door frame
- Crumbling sand mastic round a window
- Draughty sash windows at the surround
Schools such as Hordle CofE (VA) 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
- Are they insured?
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- How long the guarantee is

What happens if it’s left?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In an older home around Hordle, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. For a job in Hordle, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Let us know about parking restrictions

FAQs for Hordle
Is sand mastic in a coastal place like Hordle any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Will you come out to Hordle?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will advise.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.

What sand mastic looks like in Hordle
Hordle is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Highcliffe Castle (about 4.4 miles west) nearby, there’s older building stock in the area around Hordle as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near New Milton station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
