How we handle facade sealing in Little Amwell
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on stone and brick facade joints, perimeter joints where frames meet the structure and coping and flashing joints, and the failures we are asked to look at most are failed sealant on precast panel joints and draughts around frames and panels. A single leaking joint is often how a building in Little Amwell first comes to us: we look at the rest while we are there and tell you what we find.
Sites around smaller places like Little Amwell can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
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.

Advice
When something else is needed
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Work on the window or framing system itself
- Providing access systems for the work
- Damaged frames that need replacing
If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.

Facade sealing around Little Amwell: what changes locally
Little Amwell sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Little Amwell has several hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
For contractors at a school such as Hertford Heath Primary and Nursery School, sealing has to be finished before term starts. Further education sites such as Hertford Regional College (to the south of Little Amwell) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Questions we are asked in Little Amwell
Is Little Amwell too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

What will the job cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.
Is old mastic on our building likely to contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When to call us in Little Amwell
Adhesive failure, where the sealant peels away from one face, normally comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.
Site and facilities staff are often the first to spot these:
- Failed sealant on precast panel joints
- Perimeter sealant that has split or peeled away
- Old perimeter mastic that has dried out
- Perimeter joints where frames meet the structure
For contractors refurbishing units at places like Taylor Trading Estate, 1.5 miles to the north-west of Little Amwell, the mastic covers cladding panels, roller-door and window perimeters.

Why act early in Little Amwell
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Older rural buildings around Little Amwell move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules.
How the job changes by surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.
Coping and flashing joints
Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.
