FAQs for Peasemore
What guarantee comes with sand mastic in Peasemore?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you do sand mastic in Peasemore?
Yes, Peasemore is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Peasemore.
How we handle sand mastic in Peasemore
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We’re often asked to deal with crumbling sand mastic round a window and a silicone bead on a sash window that spoils the look, across brick reveals, timber door frames and tenement windows.
Mastic can only go onto a dry, clean joint, so window work in Peasemore is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Peasemore as everywhere else we work.

What the job involves on each surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.

Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Peasemore can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Windows and doors in Peasemore
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Barnabas include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Around Peasemore, as everywhere, sand mastic is only as good as the preparation behind it.

The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Peasemore, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Tell us if parking is tricky
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, 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.
How we quote for sand mastic
Call for a quick quote. The main things that affect it are:
- How many areas need sealing
- Whether there’s mould to deal with
- How easy the joints are to reach
- The size of the job
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Where the property is
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
- Crumbling stone or brickwork round the window
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
