How we handle commercial sealant contractors in Stratfield Saye

Sealant joints are easy to overlook until one lets water in, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. We work on washrooms and tea points, floor and threshold joints and movement joints in walls and floors, and what we’re called in for most is damp patches where an external joint has failed and frame mastic that has hardened and come away from the wall. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Stratfield Saye is the same: the right product in a properly prepared joint.

The most common commercial job in Stratfield Saye 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.

In and around smaller places such as Stratfield Saye, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

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

If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Surfaces we seal

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

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Check joints after other trades have worked nearby
  • Keep a record of which joints were resealed and when
  • Act on the first lifting edges rather than waiting
  • Have extract fans checked so wet areas dry out

Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.

Sealant rarely fails all at once across a building. A few splits this year typically mean more next year. We will tell you which sealant joints need doing first and which can wait.

FAQs: Stratfield Saye

Can you supply sealant in our brand colour for a site in Stratfield Saye?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Does your area include sites such as Campbell Court Office Park, near Stratfield Saye?

Yes, sites like Campbell Court Office Park are within our area, along with the rest of Stratfield Saye. A few photographs and the unit address let us price the work.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you check for asbestos before removing sealant?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Can you take on work for an FM or managing agent?

Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Stratfield Saye, 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. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints

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. Getting these wrong typically costs more in the end than doing them right.

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, which is what makes a joint last.

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Induction, permit and paperwork requirements
  • The product specified
  • Working within restricted access windows
  • Backing rod, priming and other preparation

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Details that help us quote

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

  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • Clear photographs of the problem areas
  • The site address and postcode

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, ring 01277 525 020 or send photos by email.

Why it’s worth doing now in Stratfield Saye

A cheaper quote sometimes means the old bead stays in. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation. Older rural buildings around Stratfield Saye move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

What you get with us

  • Constructionline member for supplier checks
  • One number for every site we cover
  • Over 20 years of commercial sealing
  • CHAS accredited
