DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Sand mastic in Philpstoun
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. Common call-outs are for draughts and rain around sash boxes and patchy fillers round a sash window, across brick reveals, period & listed homes and timber door frames.
Mastic can only go onto a dry joint, so outside work in Philpstoun depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes as standard, so you are covered after we have gone.

What else we do in Philpstoun
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Landlords and letting agents in Philpstoun can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
What sand mastic looks like in Philpstoun
Philpstoun is close to 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Letting a property close to Linlithgow station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Pardovan Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Advice
How we quote for sand mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- The product the joint needs
- Working hours on commercial sites
- How many areas need sealing
- The size of the job
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Helping us quote
What to tell us when you ask for a quote:
- Where the property is
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Timber that has rotted
- Masonry that needs repairing
- Sashes that rattle, stick or won’t open
If you are not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before you book.

Why it’s worth doing now in Philpstoun
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In an older home around Philpstoun, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Do you need sand mastic in Philpstoun?
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint and we normally remove them.
The problems people usually mention when they call include:
- Mastic dropping out of the joint
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
If you look after a building such as Winchburgh Academy, the mastic around its windows and doors needs looking after like any other building’s.

Philpstoun: your questions answered
Does the coastal weather in Philpstoun affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Will you come out to Philpstoun?
Yes. Philpstoun is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
What guarantee comes with the work?
Every job comes with our one-year guarantee.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Philpstoun.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Philpstoun.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
