Sealant specialists in Temple End

How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface. If you are dealing with expansion joints with the sealant torn out and mouldy silicone around WCs, urinals and vanity tops, we can put it right, on washrooms and tea points, external facade joints and movement joints in walls and floors alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Temple End it comes down to the same thing: the right product in a properly prepared joint.

Occupied buildings in Temple End need the work phased: we agree the order with you and hand back each area with its cure time.

Rural business units near smaller places such as Temple End are frequently converted agricultural buildings. 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.

Work we carry out in Hertfordshire comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email the details over and we will arrange a return visit.

How a job runs

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Temple End, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  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. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Make sure the joints can be reached
  • Confirm the product named in the specification

Advice

When to bring in a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Surface by surface

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, often in a colour to suit the brand finish. We will confirm the colours available for the specified product.

Your questions answered

Is Temple End too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you offer colour-matched sealant for buildings in Temple End?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.

What about asbestos in old mastic?

We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility, and we don’t remove asbestos-containing materials.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Will the building have to shut during the work?

That comes down to planning: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we will work around it.

Do you hold CHAS accreditation?

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

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

After the work

Once the work is signed off, a little attention goes a long way:

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Check joints after other trades have worked nearby
  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Add sealant to the planned maintenance inspection list

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Backing rod, priming and other preparation
  • Working within restricted access windows
  • How much existing material needs removing
  • The site’s rules and procedures

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

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Specification clauses that apply
  • Drawings or a marked-up plan, if available

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send details through our quote form with what you know.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Broken glass or blown double-glazed units
  • Old mastic that tests positive for asbestos
  • Cracking that needs a structural engineer to look at it

If you are not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer.
