Sealant specialists in Shelley

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Shelley, ring 01277 525 020 or email the details over with the site addresses. We work on kitchen worktops and splashbacks, floor and threshold joints and external facade joints, and what we’re called in for most is window and door perimeter joints that have cracked open and layers of sealant, all of them failing. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Shelley, that means joint design, primers and backing rod as standard.

The most common commercial job in Shelley is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Business units in the countryside around places like Shelley are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What affects the price in Shelley

Each job is priced on its own details. The things that drive the figure:

  • Site requirements such as inductions and permits
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition
  • Which sealant the job calls for

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Before you send an enquiry

We can often quote from photographs and a few details. Please tell us:

  • When you need the work done
  • Whether the building will be occupied during the work
  • Any specification or named product
  • Clear photographs of the problem areas

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Walls or slabs moving more than any sealant can take
  • Leaks from pipework, wastes or valves (that’s plumbing)

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

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

How the job changes by surface

Fire-rated seals where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, and we’ll tell you if the detail calls for something else.

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, phasing the rooms so not every toilet is closed at once.

Common problems we fix in Shelley

In wet areas the enemy is usually mould rather than movement. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead; when mould is in the body of the sealant, no cleaner will shift it. The fix is a new bead of anti-mould sanitary silicone.

Things that normally lead to an enquiry:

  • Smeared sealant across finishes from a rushed job
  • Gaps behind commercial kitchen worktops and sinks
  • Frame mastic that has hardened and come away from the wall
  • Earlier reseals applied straight onto the failed bead

Whatever the building in Shelley, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • What the guarantee covers, and for how long
  • Their plan for phasing and protecting the area
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Working on commercial sites near Shelley

Central London is about 21 miles from Shelley. Business parks and retail centres are common around the capital’s motorway corridors. If you have premises across the region, one contractor can cover them all. Rainfall across the South East, Shelley included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

On estates like Hallsford Bridge Industrial Estate (1.7 miles south-east of Shelley), the office and welfare end of each unit has its own sealant to maintain.

Shelley is about 7 miles south-east of Harlow, in Essex. We cover Shelley and the rest of Essex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Essex, 644 places are covered, Shelley among them. Sites around London have their own page, roughly 21 miles from Shelley.

FAQs: Shelley

Can the sealant on our Shelley premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we’ll confirm what’s available for the product.

Can you work at a site such as Hallsford Bridge Industrial Estate, by Shelley?

Yes. We cover Shelley and the area around it, including industrial estates, business parks and retail parks such as Hallsford Bridge Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

What guarantee do you give on resealing?

Each job sits under our 12-month guarantee from handover. Keeping joints clean and inspected helps them last well beyond that.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What site paperwork can you provide?

Send your site requirements with the enquiry. For older buildings we will ask for the asbestos register, plus your site induction rules.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

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. Smaller jobs around Shelley can be grouped with others nearby. You will have a fixed quote before work starts.

  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. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Flag any permit to work we’ll need
  • Share the asbestos register for older buildings
  • Point out parking and an unloading spot
