Mastic around window and door frames, sills and patio doors for Rawreth, backed by a one-year guarantee. Call for a quick quote.

Why deal with it now?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Rawreth, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- More than 20 years in sealant work
- Fully insured
- Neat joints and a tidy finish
- Homes, businesses and hotels

Window mastic for homes and businesses in Rawreth
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on aluminium frames, composite doors and patio & French doors, and people most often call us about hard, cracked sealant around windows and draughts coming in around windows and doors.
Around Rawreth, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

How it works
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 for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. For a village or hamlet like Rawreth, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

Advice
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- How easy the joints are to reach
- How much there is to do
- The product the joint needs
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- The address or postcode of the job
- The rough size of the job
- The problem you’ve noticed
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or send us an email.

How to look after the new joints
So the new joints stay in good condition:
- Look round the frames every year or so
- Repaint timber before it’s bare
- Make sure the drainage slots are not blocked
- Don’t use solvent cleaners on the joint
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.

Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long should I leave it?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
What window mastic looks like in Rawreth
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.
If you let a flat or house near Battlesbridge station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Our Lady of Ransom Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Honest limits
A few problems are outside what sealant work can do:
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
- Broken hinges, locks or handles
