Our applicators work in Rockford on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

What we’re called out for in Rockford
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Common reasons people contact us are:
- Old cement repairs round a window that have failed
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
If you live in an older home near Church of St Martins, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- How the colour is chosen
- Whether the sealant suits the joint
- Is VAT in the price?
- Is the old sealant removed completely?
About our sand mastic in Rockford
Sand mastic does not last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We work on period & listed homes, sash and case windows and stone surrounds, and common reasons people get in touch are old cement repairs round a window that have failed and silicone on a period window that looks wrong.
In a village or hamlet like Rockford, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, in Rockford and everywhere else we cover.

Questions from Rockford
Do you cover smaller places like Rockford?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with sand mastic in Rockford?
All our work, in Rockford and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Different surfaces, different methods
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
How we quote for sand mastic
For a quick quote, just ask. The main things that affect it are:
- How much there is to do
- The old material and how stubborn it is
- Whether the work is at height
- When we can work, for business premises
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we will take it from there.
The process
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. For a village or hamlet like Rockford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
Getting a quote

What we can’t put right
We’d rather tell you now than do work that won’t last, so these are the limits:

- Broken panes
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Where we work in Rockford
- Brick reveals
- Sash and case windows
- Period & listed homes
- Timber door frames
- Tenement windows

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Keep modern sealant off the mastic
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Rockford homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Poulner Junior School, the mastic around its windows and doors needs looking after like any other building’s.

Why act early in Rockford
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Older cottages and farmhouses around Rockford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
