What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. In a small place like Hale, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.

About our sand mastic in Hale
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on period & listed homes, brick reveals and sash and case windows, and the jobs we see most are cement or filler used on old window joints that has cracked and wind and rain getting in round a sash window.
Homes in small places like Hale often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, large or small.

Sand mastic in Hale: local notes
Hale is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Restoration House (about 2.7 miles north-west) nearby, there’s older building stock in the area around Hale as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Kingfisher Community Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Do you need sand mastic in Hale?
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
If you let a flat or house near Gillingham (Kent) station, any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before you book
- Whether they seal over old material or remove it
- What happens if the job turns out different
- How the joint is cleaned and prepared
- What guarantee comes with the work
Why act early in Hale
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Hale, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

When something else is needed
A few problems are outside what sealant work can do:
- Decisions on consent for listed homes
- Sashes that rattle, stick or won’t open
- Cracked or broken glass
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Joints and surfaces we work on
- Tenement windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Timber door frames
- Sash and case windows
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Ask the planning authority about consent for listed or conservation-area homes
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Don’t paint over the new mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

What affects the quote in Hale
For a quick quote, just ask. What matters most is:
- Which sealant suits the joint
- Access and height
- The number and length of the joints
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- The rough size of the job
