How we quote for sand mastic
We don’t publish a price list. The quote depends on:
- How easy the joints are to reach
- The type of sealant required
- The number and length of the joints
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work before giving you a price.
How we handle sand mastic in Preston Candover
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you have gaps between timber frames and stone or brick and cement or filler used on old window joints that has cracked, we can put it right, whatever the surface.
Somewhere as small as Preston Candover, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

FAQs for Preston Candover
What guarantee comes with sand mastic in Preston Candover?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Preston Candover within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long does sand mastic take?
Typically it takes a few hours per window, depending on the condition of the joints. Bigger jobs take longer.
How much does sand mastic cost in Preston Candover?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Leave it or put it right?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Around Preston Candover, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet

When to call us in Preston Candover
Water gets into small cracks in the mastic and loosens it further. Exposed elevations generally fail first.
It’s worth asking for a quote if you see:
- Failed mastic on an exposed elevation
- Mastic that needs renewing before redecorating
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
In the older streets around Church of St. Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.
Questions to ask before you book
- How the joint is cleaned and prepared
- The length of the guarantee
- Whether you can choose the colour
- When the joint can take water or movement
Preston Candover homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hall Place (about 3.6 miles east) are a reminder that the area around Preston Candover has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Preston Candover Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a single window, longer for several. In a small place like Preston Candover, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Move anything stored near the joints
