How the job changes by surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
Facade sealing in Ash
Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. Site teams most often ask us about previous reseals run over old sealant and cladding panel joints that have opened up, across stone and brick facade joints, window and door perimeters and perimeter joints where frames meet the structure. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Ash is the same: the right product in a properly prepared joint.
For a site near Ash, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep the sealant details on the building file
- Insist on a full cut-out when joints are renewed
- Share access with other external trades
- Confirm the survey covers external sealants in older buildings
Record the sealant type and date on the building file. Future work can then match the product and colour.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Ash, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open
- Tell us your opening times and when work is allowed

Advice
Why act early in Ash
Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Converted and older buildings near places like Ash tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Building and refurbishing in Ash
Rainfall across the South East, Ash included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. There are a number of hotels within about 2 miles of Ash. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
School extensions, at buildings such as New Ash Green Primary School, normally run to the summer holidays, mastic included. With historic properties like Lullingstone Castle, 4.2 miles west of Ash, in the area, refurbishment work often meets old masonry that needs compatible sealants. When units on a site such as Heaver Farm Trading Estate (to the north of Ash) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Ash is about 6 miles south-west of Northfleet, in Kent. Ash sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Kent, 931 places are covered, including Ash. Sites around London have their own page, about 19 miles away.

What sets the cost
What shapes the price:
- Travel to remote or island sites
- Whether the work must be split into stages
- Access and working height
- Whether old sealant has to be cut out first
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- Specification clauses that apply
- The postcode of the building
- What the building is and how it’s used
- A wide shot and a close-up of the area
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Questions about Ash
Is a hospital such as Darent Valley Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Is Ash off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can call the office on 01277 525 020 or email us to arrange a visit. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. That is what makes the new joint last.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
