Sibford Ferris questions
Is Sibford Ferris in your area for sand mastic?
Yes. Our work covers London and the South East, and Sibford Ferris is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Is Sibford Ferris within the area you cover?
Yes, Sibford Ferris is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you have insurance?
Yes. Mr Mastic is fully insured.
How much does sand mastic cost in Sibford Ferris?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why act early in Sibford Ferris
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Older cottages and farmhouses around Sibford Ferris can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ask us before painting near the mastic
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
Avoid painting over the new mastic, which is the traditional advice. If you’re redecorating, ask us first.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

What else we do in Sibford Ferris
Windows and doors in Sibford Ferris
With historic houses such as Broughton Castle (about 3.8 miles east) nearby, there’s older building stock in the area around Sibford Ferris 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Sibford School? Then its window and door frames need their mastic kept sound, just like a home’s.
