Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Work in places the size of Nyetimber is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

  • Point out parking and an unloading spot
  • Confirm the product named in the specification
  • Agree which areas must stay open

Commercial sealant contractors for commercial buildings in Nyetimber

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely, then both faces are cleaned back to sound, dry material with no dust or grease on them. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. We work on external facade joints, window and door perimeters and kitchen worktops and splashbacks, and the usual reasons a site gets in touch are messy, uneven beads from earlier work that let the building down and damp patches where an external joint has failed. Most enquiries from Nyetimber start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Quotes for commercial sealant in Nyetimber can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.

Around smaller places such as Nyetimber, small firms often work from converted barns, yards and rural units. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Nyetimber: questions and answers

Is a smaller place like Nyetimber outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does your area include sites such as Enborne Business Park, near Nyetimber?

Yes. Our area takes in Nyetimber and its surroundings, with estates and business parks such as Enborne Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Which site documents can you send us?

Let us know your requirements when you ask for a price, and we will confirm the RAMS, insurance and CSCS details with the quote. From you, we’ll need the asbestos information for older buildings and any site rules.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Could the old sealant in an older building contain asbestos?

On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder.

Is failed sealant stripped out, or sealed over?

Full removal is part of every quote. A bead laid on old silicone peels away and isn’t worth paying for.

Why act early in Nyetimber

Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings. You notice the difference years later, not on the day. For buildings in places like Nyetimber, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

A quote for sealant joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Why us?

  • Sealing commercial buildings since 2005
  • Clear, fixed quotes
  • Matching to RAL references, product permitting
  • Fully insured, including public liability cover

Read our cost guide or our accreditations.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Broken glass or blown double-glazed units
  • Suspect materials that need testing and specialist removal
  • Walls or slabs moving more than any sealant can take

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

What we seal

  • Floor and threshold joints
  • Window and door perimeters
  • Movement joints in walls and floors
  • Washrooms and tea points
  • External facade joints
  • Kitchen worktops and splashbacks

Common problems we fix in Nyetimber

The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

Common reasons buildings call us in:

  • Window and door perimeter joints that have cracked open
  • Sanitary sealant that has gone black and patchy
  • Smeared sealant across finishes from a rushed job
  • Wall and floor joints that have lost their seal

If you run an office at a site such as Enborne Business Park, which lies west of Nyetimber, the sealant at reception desks, tea points and frames ages with each fit-out.

Comparing quotes

  • What the guarantee covers, and for how long
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

What sets the cost

The price varies from site to site. It mainly depends on:

  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • The total length or number of joints

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Sending details for a quote

A few photographs plus some basic facts will normally do. It helps to include:

  • Whether an asbestos survey exists
  • Clear photos of the problem areas
  • The site address and postcode
  • Anything awkward about access or site hours

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send details through our quote form.

What Nyetimber’s businesses ask us to seal

Nyetimber sits close to the coast, within about 1 mile. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. Sea-facing elevations are normally where failed joints show first. Nyetimber is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Shops and cafés around stations like Bognor Regis station (to the east of Nyetimber) trade from early, so work is timed around them. Sites a few miles apart, such as Enborne Business Park and Ferry Yard Industrial Park, can share one programme and one point of contact.

Nyetimber is about 2 miles south-west of Bognor Regis, in West Sussex. Commercial clients in Nyetimber use us for work on sealant joints. Nyetimber is one of 373 places in West Sussex on our list. For work in that direction, see our Portsmouth page.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Keep barriers up until the new sealant has cured
  • Keep a record of which joints were resealed and when
  • Keep abrasive pads and scrapers off resealed joints

Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. If that happens, call 01277 525 020 or email the details over and we’ll price putting it right.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We can assess the lot and suggest what to do now and later.
