Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Allow flexibility for external sealing in damp or cold weather
- Keep finished joints away from paint, plaster and scrapers
- Brief the final clean team to avoid blades near sealant
- Record the products used in the O&M file
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.
How we handle construction mastic in Norton
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers on schemes in Norton. Most enquiries involve oversized or tapered gaps around new frames and snag items on joints that need redoing before handover, on internal decorators’ caulk, window and door perimeters and sanitary and kitchen joints. Searching for sealant specialists in Norton? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Construction in and around smaller places such as Norton is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
A 12-month guarantee applies to all our work in West Sussex. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we will arrange a return visit.

What we are called out for in Norton
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
What tends to prompt an enquiry:
- External joints sealed in damp or cold conditions that are now failing
- Failed sealant in an existing building being refurbished
- A mastic package split between trades with no clear owner
- Snag items on joints that need redoing before handover
Units on estates such as Chichester Business Park. (to the west of Norton) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- What site paperwork they can supply
- Proof of insurance
- Will CSCS-carded applicators be on site?

Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Why it’s worth doing now in Norton
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we will tell you. Older rural buildings around Norton 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.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Why us?
- Work to your specification and the manufacturer’s guidance

When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Frame gaps too wide for sealant, which the installer needs to correct
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can call the office on 01277 525 020 or email us and we will tell you honestly.
What we seal
- Internal decorators’ caulk

Sites and facades in and around Norton
Norton sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 52 miles from Norton. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
For a contractor working at a hospital such as St Richard's Hospital, 3.9 miles west of Norton, perimeter and facade sealing is planned around patients and deliveries. Older buildings in the area around Norton, such as Goodwood House, 2.9 miles north-west of Norton, need care when sealed: the product has to suit soft or historic materials.
