What window mastic looks like in Surrex
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. With historic houses such as Layer Marney Tower (about 5 miles south-east) nearby, there’s older building stock in the area around Surrex as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to St Peter ad Vincula include some older properties, and 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 Honywood Community Science School, the mastic around its windows and doors needs looking after like any other building’s.
Surrex is about 6 miles south-east of Halstead, in Essex. Surrex gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Our Essex coverage runs to 644 places, and Surrex is one of them. There’s also a page for Chelmsford, roughly 14 miles from Surrex.
Work in CO6 is quoted and booked the same way as anywhere else. Streets in the area include Old Road and Colchester Road, and we cover them all. If you’re just outside Surrex, we cover Skye Green (1 mile south-east), Broad Green (1 mile east), Stocks Green (1 mile south), Little Tey (1 mile east) and Feering (2 miles south). Larger places within reach include Colchester (8 miles east), Chelmsford (14 miles south-west), Braintree (7 miles west), Maldon (10 miles south), Witham (6 miles south-west) and Camulodunum (7 miles east).

A little further out are Laundry & Mangle Museum (1.8 miles west) and Birch Castle (5 miles south-east). Green spaces nearby include Belcher's and Broadfield Woods.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
- Ventilate rooms so frames do not stay wet inside
- Don’t use solvent cleaners on the joint
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Why deal with it now?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Older cottages and farmhouses around Surrex can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Surrex: your questions answered
Do you work for landlords with property near Kelvedon station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Is Surrex within the area you cover?
Yes. Surrex is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How long will my window job take?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
What happens on the day
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Surrex, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

Signs you need window mastic in Surrex
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Keep an eye out for these signs:
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
- Sealant in the wrong colour for the frame
Letting a property close to Kelvedon station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
What to look for in a quote
- Whether you can choose the colour
- Are they insured?
- How much experience the applicator has
- Whether they seal over old material or remove it
