About our sand mastic in Wargrave
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. If you are dealing with modern sealant on a period surround and mastic dropping out of the joint, we can put it right.
Houses in smaller places like Wargrave 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.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

FAQs for Wargrave
Can you do sand mastic in Wargrave?

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

How much does sand mastic cost in Wargrave?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.

Advice
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Why act early in Wargrave
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Wargrave, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
- Look over the window mastic once a year
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What sand mastic looks like in Wargrave
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. Historic houses like Harleyford Manor (about 4.2 miles north-east) are a reminder that the area around Wargrave has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Wargrave station, older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Robert Piggott CofE Infant School? Then its window and door frames need their mastic kept sound, just like a home’s.
