Facade sealing for commercial buildings in Brickendon
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. Most enquiries involve old perimeter mastic that has dried out and unsightly perimeter sealant on a visible elevation, on perimeter joints where frames meet the structure, shopfront frames and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Brickendon, preparation and product choice get the time they need.
In the countryside around places like Brickendon, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Contractors’ notes for Brickendon
Brickendon is in the South East, one of the UK’s drier regions. 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. Central London is about 18 miles from Brickendon. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
Extensions at sites like Hertford County Hospital (2.8 miles north of Brickendon) normally sit beside working departments, and the mastic follows strict access rules. On a campus such as University of Hertfordshire, 4 miles west of Brickendon, new teaching buildings and residences are usually built and refurbished around the academic year. Projects at colleges like Hertford Regional College, 2.4 miles east of Brickendon, tend to run to term dates, so the mastic is planned tightly.

Building owners, agents and FMs in Brickendon
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Check the asbestos register before old mastic is disturbed
- Don’t wait for a second leak before calling
- Check that rainwater leaves the facade the way it was designed to
- Never let anyone seal over old sealant
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.
Why act early in Brickendon
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Leaks travel along the structure, so the real damage is often some distance away. Converted and older buildings near places like Brickendon tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Cracked or spalling substrates that need repair before sealing
- Specialist high-level access methods
- Water getting in through cracked render or porous masonry
Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly before you book.
Surfaces we seal

- Coping and flashing joints

- Perimeter joints where frames meet the structure
How the job changes by surface
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.
Precast concrete panels
Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod.
Questions we’re asked in Brickendon
Will you take on work at estates like Mimram Road Industrial Estate, close to Brickendon?
Yes, sites like Mimram Road Industrial Estate are within our area, along with the rest of Brickendon. A few photographs and the unit address let us price the work.
Is a smaller place like Brickendon outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
How many days will you need on site?
It depends on the scope, but the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you replace failed glazing units?
No. That work needs a glazing specialist. What we seal are the joints around frames and panels across the facade.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
