Construction mastic in Horsleys Green, done properly

Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you have oversized or tapered gaps around new frames and missed perimeter joints on a new elevation, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Horsleys Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Horsleys Green, building work usually 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Specifying the product where the designer hasn’t
  • Glazing units that are cracked or misted
  • Joints damaged after sign-off by following trades

If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think.

Joints and surfaces we work on

  • Window and door perimeters
  • Sanitary and kitchen joints
  • Floor and skirting junctions
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Brick and block movement joints

Common questions from Horsleys Green clients

Does your area include sites such as Junction 5 Bates Industrial Estate, near Horsleys Green?

Do you take on work at healthcare sites like Wycombe Hospital?

What will the job cost?

There isn’t a price list, because every site is different. Send photos or drawings and we will price it at a fixed figure.

Do you use the sealant named in the specification?

The specified product is what goes in. If we think an alternative would suit better, we put it to you first.

Can fire-rated sealing at service penetrations be included?

Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we’ll confirm with the quote.

Different surfaces, different methods

Bathrooms, en suites and washrooms

Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used.

What we’re called out for in Horsleys Green

Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.

Most enquiries start with one or more of the following:

  • Internal caulk splitting as the building dries out
  • Bath and shower joints scraped during the final clean
  • Frame perimeters left unsealed or poorly sealed
  • Existing joints on a refurb that need cutting out and resealing

Recladding or extending a unit at a site like Junction 5 Bates Industrial Estate (1.6 miles north-west of Horsleys Green) brings panel joints and frame perimeters into the programme.

Comparing quotes

  • What site paperwork they can supply
  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • Whether primer will be used where the manufacturer specifies it

New build and refits around Horsleys Green

Rainfall across the South East, Horsleys Green included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Central London is about 35 miles from Horsleys Green. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

Historic houses such as West Wycombe Park House, 2.7 miles east of Horsleys Green, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Hospital estates such as Wycombe Hospital (to the east of Horsleys Green) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Keep finished joints away from paint, plaster and scrapers
  • Check frame gaps are within the sealant’s range before sealing
  • Ask cleaners to use soft cloths around fresh sealant
  • Release areas for mastic once other trades have finished in them

A new structure shifts as it loses construction moisture. The right product in each joint copes with that, but caulk in a joint that moves more than expected may crack. If that happens, let us know.

Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last. We raise them during our first walk of the area.
