Little Wymondley: questions and answers

Is a smaller place like Little Wymondley outside your area?

No. Places such as Little Wymondley are covered as much as the big towns. We cover Greater London and the counties of 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.

Must a hotel around Little Wymondley close while you work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray joints are where many washroom leaks start.

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.

What affects the price in Little Wymondley

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Travel to remote or island sites
  • The site’s rules and procedures
  • How much existing material needs removing
  • How accessible the joints are

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

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

  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • The type of building and who uses it
  • The postcode of the building

Questions to ask before you appoint anyone

Why it’s worth doing now in Little Wymondley

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Older rural buildings around Little Wymondley move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

There’s no price list, since every building and every scope is different. Call for a quote.
