Quoting for work in Parkhurst
Each job is priced on its own details. The main factors are:
- Working within restricted access windows
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
- How much there is to seal
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
The more we know, the firmer the quote. Helpful details to send:
- Whether the building will be occupied during the work
- Access details, including height
- The site address and postcode
- The asbestos register, for older buildings

About our construction mastic in Parkhurst
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal areas can typically carry on while the outside waits. Site teams most often ask us about frame gaps too wide for sealant alone and a long mastic snag list close to completion, across floor and skirting junctions, internal decorators’ caulk and cladding and panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Parkhurst it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Parkhurst, building work normally 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.

Common problems we fix in Parkhurst
A new building moves while it dries and settles. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Choosing the right product for each joint reduces that.
Look out for the following:
- Cracks opening in caulked internal joints
- Bath and shower joints scraped during the final clean
- Failed sealant in an existing building being refurbished
- External joints sealed in damp or cold conditions that are now failing
For contractors refurbishing units at places like Wakes Retail Park (1 mile south-east of Parkhurst), the mastic covers cladding panels, roller-door and window perimeters.

Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Construction mastic around Parkhurst: what changes locally
A 2-mile radius around Parkhurst takes in several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Parkhurst sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
School extensions, at buildings such as Hunnyhill Primary School, usually run to the summer holidays, mastic included. Work at a hotel such as The Bugle Hotel Tap, 1.2 miles south of Parkhurst, tends to be programmed around bookings, mastic included.

Common questions from Parkhurst clients
Is hospital work, at somewhere like St Mary's Hospital, something you do?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Parkhurst off your patch?
Not at all. Parkhurst is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Do you take on mastic snagging only?
Yes. We can work through a mastic snag list area by area before handover.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Leave it or put it right?
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Leave it late and they turn up on the snag list. One visit to deal with every failing joint makes more sense than several trips to a place like Parkhurst. Send photos of each area and we will quote for the lot.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

How the job changes by surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.
