Your questions answered
Is Breachwood Green too far out for you?
Not at all. Breachwood Green is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Barratt Industrial Park, near Breachwood Green?
Yes, sites like Barratt Industrial Park are within our area, along with the rest of Breachwood Green. To start, just give us a call on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Do you run new sealant over the existing bead?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
How we handle facade sealing in Breachwood Green
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are sealant pulling away from frames or panels and new sealant peeling off old mastic. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Breachwood Green, that means joint design, primers and backing rod as standard.
Around smaller places like Breachwood Green, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email us and we’ll arrange a return visit.

Surface by surface
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.
From enquiry to sign-off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Breachwood Green, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out 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.
- The finished joints are checked with you.
Preparing the site
- Share the asbestos register for older buildings
- Flag any permit to work we will need
- Point out any areas we must not close
Ask for a quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send photos by email.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Arranging specialist high-level access, which is planned with the client
- Joints too narrow for the movement they take, which need redesign
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer.
What we seal

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Avoid patch repairs on failed facade joints
- Record the product and colour used on each elevation
- Confirm the survey covers external sealants in older buildings
- Inspect facade joints on a regular cycle
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness.
Coordinate facade sealing with other external works. One set-up for several trades saves money and cuts time on site.
Facade sealing around Breachwood Green: what changes locally
Breachwood Green is about 28 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Rainfall across the South East, Breachwood Green included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
For contractors refurbishing units at places like Barratt Industrial Park, 2.7 miles west of Breachwood Green, the mastic covers cladding panels, roller-door and window perimeters. For contractors at a school such as Breachwood Green Junior Mixed and Infant School, sealing has to be finished before term starts. For contractors on a campus like University Of Bedfordshire, 3.6 miles to the west of Breachwood Green, facade and perimeter sealing has to fit around students and term dates.

What happens if it’s left?
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Halls, stores and units around places like Breachwood Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
