Why deal with it now?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. Converted and older buildings near places like Coryton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why us?
- One number for every site we cover
- Over 20 years of commercial sealing
- Workmanship guaranteed for 12 months
- A range of standard colours, depending on the product

Mastic sealing in Coryton, done properly
Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. The enquiries we see most involve mastic failing across several blocks on an estate and occupiers reporting cold air round windows, across external wall and movement joints, communal entrances and stairwells and window and door perimeters on blocks. Looking for mastic applicators who cover Coryton? We have been sealing commercial buildings since 2005.
For owners with a single building near Coryton, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What affects the price in Coryton
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Whether old sealant has to be cut out first
- Any access equipment needed
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- Any specification or named product
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
To get a fixed quote, call 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
What we are called out for in Coryton
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
These are often picked up first by site or facilities staff:
- Leaks at window and door perimeters
- Old repairs sealed over failed mastic
- Mastic failing across several blocks on an estate
- Cracked, hardened mastic round windows on a block
For owners of several units at places like London Gateway Logistics Park, 1.3 miles west of Coryton, one programme can deal with frame and external mastic across the lot.
What your quote should include
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
- How they handle RAMS and site documents
- Can the work be phased to keep areas open?
FAQs: Coryton
Is a smaller place like Coryton outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
We manage a building near Benfleet station. Can you help?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Will residents or tenants be disturbed?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Frames that are rotten, warped or broken
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Glazing that needs replacing
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.
Joints and surfaces we work on
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
- Communal entrances and stairwells
Looking after the joints
A few simple habits keep the new joints working:
- Avoid piecemeal callouts where you can
- Track which buildings were done and when
- Protect low-level joints in entrances
- List the paperwork your organisation requires when you send details
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
