How we handle sand mastic in Baldslow
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. If you have cement or filler used on old window joints that has cracked and open joints round the window box, we can help, whatever the surface.
Homes in small places like Baldslow often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Baldslow, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What affects the quote in Baldslow
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- The type of sealant required
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.
What we need to know
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Any previous sealing or DIY work
- The rough size of the job
- How we’d reach the joints
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or email us.
Keeping the joints in good condition
So the new joints stay in good condition:
- Inspect the joints round the windows every year or so
- Keep modern sealant off the mastic
- Get any rot dealt with first
- Do not paint over the new mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Baldslow questions
Is sand mastic in a coastal place like Baldslow any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can you help a landlord with a rental near Ore station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
How long does sand mastic take?
Most jobs take a few hours per window, depending on the condition of the joints, including preparation and clearing up. Your quote will say how long we expect yours to take.
What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Is sand mastic better than silicone for my windows?
We will talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
How the job changes by surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Windows and doors in Baldslow
Baldslow is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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 Durhamford Manor (about 3.8 miles north-west) nearby, there’s older building stock in the area around Baldslow as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as Ark Helenswood Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St John the Evangelist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. For a village or hamlet like Baldslow, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Mention any parking rules near the property
