Sand mastic in Hatchford End

We work on tenement windows, period & listed homes and brick reveals, and common reasons people get in touch are mastic round period door frames that has failed and failed mastic on an exposed elevation.
Outdoor sealant needs dry, clean surfaces, so work on frames around Hatchford End is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

What affects the cost of sand mastic
The quote reflects the job in front of us. We look at:
- When we can work, for business premises
- The type of sealant required
- How many areas need sealing
- Whether there’s mould to deal with
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- The address or postcode of the job
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Renew mastic before redecorating the windows
- Clear gutters so water does not pour onto the windows
- Check the mastic when you check the paintwork
- Find out about consent before window work on a listed home
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
What we are called out for in Hatchford End

When it is not the sealant

Hatchford End questions
Will you come out to Hatchford End?
Yes, Hatchford End is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Effingham Junction station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
How long does the job take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll say how long yours will take.
How long does sand mastic take to harden?
It skins over fairly quickly but takes longer to harden fully. We’ll tell you what to expect for your job.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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.

Hatchford End homes and the weather
Historic houses like Byfleet Manor (about 1.7 miles north-west) are a reminder that the area around Hatchford End 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
