How we handle facade sealing in Ayot Green
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. We work on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints, and the usual reasons a site gets in touch are leaks at window and door perimeters and air leaks through failed facade joints. One point of contact handles commercial sealant work in Ayot Green from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like Ayot Green, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Confirm the survey covers external sealants in older buildings
- Plan facade sealing alongside redecoration
- Keep the sealant details on the building file
- Walk the elevations once or twice a year
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.

Sites and facades in and around Ayot Green
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Ayot Green has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Work at a hotel such as The Wellington Inn Hotel, 1.4 miles north-east of Ayot Green, tends to be programmed around bookings, mastic included. Projects at colleges like Oaklands College - Welwyn Garden City Campus (1.2 miles south-east of Ayot Green) tend to run to term dates, so the mastic is planned tightly. When units on a site such as Little Ridge Industrial Estate, 2.3 miles south-east of Ayot Green, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What the job involves on each surface
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone.
Render and coated surfaces
Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.
Cost factors for facade joints
Before we quote, we look at:
- Whether old sealant has to be cut out first
- Access and working height
- The product specified
- Location, for remote and island sites
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- The product your specification calls for
- The asbestos register, for older buildings
- The site address and postcode
- Approximate linear metres or a joint schedule
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email a schedule or drawings with what you know.
Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Halls, stores and units around places like Ayot Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Why us?
- Failed material removed, not covered up
- A range of standard colours, depending on the product
- Work carried out by CSCS-carded applicators
- Work to your specification and the manufacturer’s guidance
