Commercial sealant contractors in Hamsey

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

Cost factors for sealant joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Whether old sealant has to be cut out first
  • Access and working height
  • Quantities, in metres or numbers
  • Travel to remote or island sites

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 requirements come into it too.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • What the building is and how it’s used
  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • The postcode of the building

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or send details through our quote form.

Commercial sealant contractors in Hamsey, done properly

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested. If you’re dealing with frame mastic that has hardened and come away from the wall and shrunken sealant along kitchen worktops and splashbacks, we can help, on washrooms and tea points, movement joints in walls and floors and window and door perimeters alike. Searching for sealant specialists in Hamsey? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

We price commercial jobs in Hamsey from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.

Work in smaller places such as Hamsey tends to come one building at a time: a pub kitchen, a hall, a small office. We will want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

Every job we finish is backed by a 12-month workmanship guarantee, in Hamsey as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Shops, offices and hotels in and around Hamsey

Hamsey lies roughly 42 miles out from central London. The commuter belt holds a great many offices, retail parks and business parks. Multi-site occupiers here often want one sealant contractor across all their buildings. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

If you have premises on more than one site, say at Malling Industrial Estate and Riverside Industrial Estate, one contractor and one quote can cover both. For premises near Cooksbridge station, which lies north-west of Hamsey, footfall is part of the plan: work is phased so shops and offices keep trading.

Hamsey is about 1 mile north of Lewes, in East Sussex. Commercial clients in Hamsey use us for work on sealant joints. Our East Sussex coverage takes in 308 places. We also cover Brighton, some 7 miles away.

Work on sealant joints is covered throughout BN8, whatever the building. We also cover Offham (1 mile south-west), South Malling (1 mile south), Lewes (1 mile south), Cliffe (2 miles south) and Southover (2 miles south). A short drive away, we cover Eastbourne (14 miles south-east), Seaford (9 miles south-east), Hailsham (11 miles east), Crowborough (13 miles north-east), Uckfield (7 miles north-east) and Newhaven (7 miles south).

Site staff or a sealant specialist?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Signs you need commercial sealant contractors in Hamsey

Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade all let go sooner than they should. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.

Most enquiries start with something like this:

  • Messy, uneven beads from earlier work that let the building down
  • Wall and floor joints that have lost their seal
  • Gaps behind commercial kitchen worktops and sinks
  • Leaks that seem to come through a sealant line

Industrial estates such as Malling Industrial Estate, 1.3 miles to the south-east of Hamsey, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they handle RAMS and site documents
  • Their public liability cover
  • How the joint faces will be prepared and primed

Questions to ask before you appoint anyone

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Cracking that needs a structural engineer to look at it
  • Suspect materials that need testing and specialist removal
  • A dripping trap, valve or pipe behind a fitting

If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

What we seal

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

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Hamsey, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First, details reach us through the quote form or 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. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work
  • Make sure the joints can be reached

Common questions from Hamsey clients

Can you work at a site such as Malling Industrial Estate, by Hamsey?

Yes. Estates, retail parks and business parks around Hamsey, Malling Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

Must a hotel around Hamsey close while you work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Can you supply RAMS and insurance details?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. From you, we will need the asbestos information for older buildings and any site rules.

What guarantee do you give on resealing?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

How long does a typical visit take?

That varies with the scale of the job, but the work usually takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

How is commercial sealant work priced?

Send photos, drawings or a list of locations through the quote form on this site. If a visit is needed we will book one, and a fixed quote follows.

Do you work for facilities managers and managing agents?

Yes. A large share of our work comes through facilities managers, managing agents and landlords as well as contractors. Tell us how you issue work and we will fit in.

What happens if it’s left?

Putting off a reseal typically moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, and the bill then involves other trades. Resealing while only the sealant has failed keeps the job small. Halls, stores and units around places like Hamsey may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
