How we handle sand mastic in Little Bardfield
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on timber door frames, brick reveals and sash and case windows, and people most often call us about mastic dropping out of the joint and silicone on a period window that looks wrong.
Around Little Bardfield, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Leave it or put it right?
Filling over old, loose mastic does not last. We remove the loose material first so the new mastic stays put. Older cottages and farmhouses around Little Bardfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Experience in homes, commercial sites and hotels
- Quality sealants from Arbo and Everbuild
- 12-month guarantee on every job

In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.

Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
Windows and doors in Little Bardfield
Historic houses like Horham Hall (about 4.5 miles west) are a reminder that the area around Little Bardfield 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’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Great Bardfield Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
How we quote for sand mastic
We quote each job individually. This is what makes a difference:
- How many areas need sealing
- Access and height
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Roughly how big the job is
- Pictures of the joints, sent by email
- The problem you’ve noticed
- How we’d reach the joints
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job and send pictures if you have them.
How to look after the new joints
To keep the joints looking good and working properly:
- Ask the planning authority about consent for listed or conservation-area homes
- Leave the new mastic unpainted
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Common problems we fix in Little Bardfield
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Keep an eye out for any of the following:
- Mastic that needs renewing before redecorating
- Draughts and rain around sash boxes
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
For an older house near a landmark such as Church of St Katharine, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before booking
- Who does the work, and how experienced they are
- Whether you can choose the colour
- Is the old sealant removed completely?
- Is VAT in the price?
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours per window, depending on the condition of the joints. Somewhere as small as Little Bardfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
