Why it’s worth doing now in Porchfield
Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after. Where it helps, we quote a patch and a full reseal side by side. Older rural buildings around Porchfield 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.
We don’t publish prices, since every building and every scope is different. Call for a quote.

Commercial mastic work in Porchfield
We’ve applied sealant on commercial sites for over 20 years, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. Most enquiries involve gaps behind commercial kitchen worktops and sinks and untidy joints in a reception, shop floor or lobby, on movement joints in walls and floors, kitchen worktops and splashbacks and washrooms and tea points. Most enquiries from Porchfield start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Multi-site clients with buildings in and around Porchfield can put several sites on one programme, so standards and paperwork match across every site.
Business units in the countryside around places like Porchfield are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
Whoever the client is, the cover is the same: 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.

From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from part of a day on a short run of joints to several weeks on a large phased package. For work around Porchfield, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- You send photographs, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
What we need from you
- For older buildings, check the asbestos register before work
- Make sure the joints can be reached
- Explain the parking and delivery arrangements

Advice
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Structural cracks or movement the joints weren’t designed for
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Broken glass or blown double-glazed units
If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Movement joints in walls and floors
- Floor and threshold joints
- Kitchen worktops and splashbacks
- External facade joints
- Window and door perimeters
- Washrooms and tea points
Surface by surface
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Porchfield: questions and answers
Do you cover business parks and estates near Porchfield, such as Porchfield Business Park?
Yes. Estates, retail parks and business parks around Porchfield, Porchfield Business Park among them, are all within reach. A few photographs and the unit address let us price the work.
Is Porchfield too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Could the old sealant in an older building contain asbestos?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What affects the price in Porchfield
We price every job individually. The main factors are:
- Travel to remote or island sites
- Removal of failed or old sealant
- Working within restricted access windows
- The size and state of each joint
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Any specification or named product
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- Where the site is, with the postcode
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, photographs and a description will do.

Each new occupier on a park like these tends to refit, from reception to staff kitchen.
