Sand mastic for sash & case windows in Wickham, Hampshire
Traditional burnt sand mastic around sash and case windows and doors in stone and brick in Wickham, with a one-year guarantee on every job. Call for a quick quote.
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
- Mastic worn away on windows facing the weather
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
- Plan mastic work ahead of painting
- Take care around the mastic when scraping paint
Avoid painting over the new mastic, which is the traditional advice. If you’re redecorating, ask us first.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
About our sand mastic in Wickham
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on period & listed homes, tenement windows and sash and case windows, and people most often call us about weathered mastic on the most exposed windows and window mastic to renew ahead of painting.
In a smaller place like Wickham, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Whatever the size of the job, it’s backed by our one-year guarantee.

The process
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. A visit to Wickham is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.

Do you need sand mastic in Wickham?
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Common reasons people contact us are:
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
- Weathered mastic on the most exposed windows
- Tired mastic found when preparing windows for paint
In the older streets around Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Are they insured?
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared

Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
For landlords and businesses

For anyone letting property in or around Wickham, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
