Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Group repairs into a planned programme
- Keep bins and bikes away from communal door frames
- Keep a record of when each building was resealed
- Share your contractor requirements early
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
Mastic sealing in Redbridge, done properly
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. Site teams most often ask us about communal area joints that look neglected and failed external movement joints, across balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks. For commercial sealant work in Redbridge, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For buildings around smaller places like Redbridge, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
Our workmanship is guaranteed for 12 months, in Redbridge as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Frames, entrances and external joints in Redbridge
At about 52 miles from central London, Redbridge is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property. Redbridge sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
Churches, halls and community buildings such as St Luke's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Site managers at schools like New Hinksey Church of England Primary School can fit frame mastic into the summer works.

Questions about Redbridge
Can work in a care setting near Redbridge go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.
Is a smaller place like Redbridge outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Substrate edges that need repairing first
- Glazing that needs replacing
- Failed window or door frames, which need a window contractor
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly before you book.

Why deal with it now?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. For buildings around smaller places like Redbridge, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Cost factors for mastic joints
A fixed quote reflects the actual work. It takes account of:
- Access and working height
- How much existing material needs removing
- Phasing around occupants
- How much there is to seal
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
