What affects the cost of sand mastic

- Whether old sealant or filler has to be cut out
- How many areas need sealing
- When we can work, for business premises
- Access and height
Doing several joints on 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.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- The problem you’ve noticed

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
- Have rotten timber repaired before new mastic goes in
- Find out about consent before window work on a listed home
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
