Sand mastic for homes and businesses in Great Bentley
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. Typical jobs include gaps round a timber door in stone or brick and mastic worn away on windows facing the weather, across period & listed homes, brick reveals and stone surrounds.
Houses in smaller places like Great Bentley can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Each job carries a 12-month guarantee.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Do not run silicone over sand mastic
- Renew mastic before redecorating the windows
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.

Your questions about sand mastic in Great Bentley
Is Great Bentley within the area you cover?
Yes, Great Bentley is covered. Our work covers 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 Great Bentley station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Is the work guaranteed?
All our work has a 12-month guarantee, and we’re fully insured.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. For a job in Great Bentley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us if parking is tricky
- Mention any tricky access
Getting a quote
Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll take it from there.
Advice
Why act early in Great Bentley
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In an older home around Great Bentley, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
