Sand mastic in Brook Street
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. If you have modern sealant on a period surround and old cement repairs round a window that have failed, we can put it right, whatever the surface.
Homes in small places like Brook Street often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, it’s backed by our 12-month guarantee in Brook Street and across Essex.

Brook Street questions
Do you cover smaller places like Brook Street?
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.
I let a flat near Brentwood station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is it worth trying 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.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.

What we do, step by step
We bring everything the job needs with us. 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. Somewhere as small as Brook Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on
- Tell us about any water getting in

Why deal with it now?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Where a wall is exposed, as many are in small places like Brook Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.
What you get with us

DIY sealant or a professional job?
What a professional job adds is preparation and the right 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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Landlord and commercial work in Brook Street
Housing providers, facilities teams and property managers book us too in Brook Street and across Essex. Several sites can be quoted together, and we are fully insured.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What affects the cost of sand mastic
Every job gets its own quote. These are the things that affect it:
- The number of rooms or windows
- Mould in or behind the old joints
- How much there is to do
- Any working-time requirements on site
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- If someone has resealed it before
- A few pictures by email, if you can
- What’s wrong with the joints now
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.
Windows and doors in Brook Street
Historic houses like Hare Hall (about 3.2 miles south-west) are a reminder that the area around Brook Street has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Holly Trees Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Brentwood station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
