About our construction mastic in Lagness
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal areas can normally carry on while the outside waits. If you are dealing with window and door perimeters that won’t pass inspection and snag items on joints that need redoing before handover, we can put it right, on floor and skirting junctions, brick and block movement joints and cladding and panel joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lagness is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like Lagness, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we will come back to it.

Sites and facades in and around Lagness
Lagness is within about 2 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Lagness is about 56 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
For a contractor working at a hospital such as Bognor Regis War Memorial Hospital, 2.4 miles to the east of Lagness, perimeter and facade sealing is planned around patients and deliveries. On a campus such as University of Chichester, 1.3 miles north of Lagness, new teaching buildings and residences are typically built and refurbished around the academic year.

Lagness: questions and answers
Does a coastal location like Lagness affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is Quarry Lane Industrial Estate, near Lagness, within your area?
Yes, sites like Quarry Lane Industrial Estate are within our area, along with the rest of Lagness. Send details of the unit and the work through our quote form for a quick quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is colour matching possible?
It depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can staff carry on working while you’re here?
In the majority of cases, yes. Phased work can be planned so areas stay in use.

What we are called out for in Lagness
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
Things that normally lead to an enquiry:
- Early adhesion failures on new external joints
- Perimeter gaps outside the sealant’s range
- Bath and shower joints scraped during the final clean
- Missed perimeter joints on a new elevation
Projects at colleges like West Sussex Alternative Provision College (1.7 miles north-west of Lagness) tend to run to term dates, so the mastic is planned tightly.

- Whether their applicators hold CSCS cards
- Their public liability cover
- Are they CHAS accredited or on Constructionline?
Leave it or put it right?
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple and a consistent finish. For buildings around smaller places like Lagness, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
There’s no price list, since every building and every scope is different. Call for a quote.

Then the right materials arrive with us.

Advice
Building owners, agents and FMs in Lagness
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Frame gaps too wide for sealant, which the installer needs to correct
- Deciding which fire-stopping product a penetration needs
- Joints damaged after sign-off by following trades
If you’re not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.
Joints and surfaces we work on
- Internal decorators’ caulk
- Sanitary and kitchen joints

How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- The size and state of each joint
- The total length or number of joints
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- Any dates the work must fit around
- Any specification or named product
- Whether an asbestos survey exists
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
