Common questions from Wych Cross clients

Can you work on a hospital site such as Queen Victoria Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Forest Row Business Park, by Wych Cross?

Yes. Our area takes in Wych Cross and its surroundings, with estates and business parks such as Forest Row Business Park included. A few photos and the unit address let us price the work.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote.

Why has the sealant in our expansion joints split?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

Different surfaces, different methods

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again.

What sets the cost

To price the job, we consider:

  • Removal of failed or old sealant
  • Which sealant the job calls for
  • Quantities, in metres or numbers
  • Whether the work must be split into stages

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Asbestos survey details if the building is older
  • The postcode of the building
  • Clear photographs of the problem areas
  • Any specification or named product

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or send details through our quote form to discuss it first.

Why it’s worth doing now in Wych Cross

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. One visit to deal with every failing joint makes more sense than several trips to a place like Wych Cross, rather than one at a time. Send photos of each area and we will quote for the lot.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • Fully insured, including public liability cover
  • Over 20 years of commercial sealing
  • CHAS accredited contractor
  • Failed material removed, not covered up

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Jobs in and around smaller places like Wych Cross are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work

Getting a fixed quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Advice

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Avoid parking heavy plant or pallets on joint lines
  • Look over external and deck joints after a hard winter
  • Raise snow-clearing blades over deck joints where possible
  • Put movement joints on the planned maintenance inspection round

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can phone 01277 525 020 or send photos by email and send a picture.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load. A sound seal keeps the joint working.
