Why act early in Lower Green
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. In a small place like Lower Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Why choose Mr Mastic in Lower Green
- We never seal over old sealant
- We’re fully insured
- Approved under the ARBOMaster scheme

Sand mastic in Lower Green
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on tenement windows, timber door frames and stone surrounds, and the jobs we see most are cracked mastic round a front door frame and mastic worn away on windows facing the weather.
Around Lower Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Every job is covered by a 12-month guarantee, wherever you are in Hampshire.

What affects the quote in Lower Green
Every job gets its own quote. This is what makes a difference:
- Working hours on commercial sites
- The product the joint needs
- Whether the work is at height
- How much there is to do
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
To make quoting easier, please include:
- Any previous sealing or DIY work
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or email us.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ask us before painting near the mastic
- Get any rot dealt with first
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
How the job changes by surface
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job normally takes a few hours for a single window, longer for several, and we tell you how long to leave it before we go. In a small place like Lower Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
