Coloured sealant near Purley on Thames

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Leave it or put it right?

A standard colour is quicker to source, though not always right. On visible work, the small extra effort of a colour from the product’s range pays off at handover. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

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.

Why appoint us

  • CHAS accredited contractor
  • Colour agreed before work starts

Coloured sealant in Purley on Thames

Coloured sealant work ranges from a new shop fit to replacing failed joints on an existing building. On resealing, matching the existing colour is often as important as the seal itself. Most enquiries involve weathered sealant that no longer matches and failed coloured sealant that has split or peeled, on cladding panels, hotel bathrooms and public areas and office fit-out finishes. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Purley on Thames, that means joint design, primers and backing rod as standard.

Around smaller places such as Purley on Thames, small firms often work from converted barns, yards and rural units. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • The total length or number of joints
  • Location, for remote and island sites
  • Which sealant the job calls for
  • The size and state of each joint

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • The postcode of the building
  • Specification clauses that apply
  • Whether an asbestos survey exists
  • The type of building and who uses it

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Look at the cured colour before the full run
  • Standardise colours across a portfolio
  • Keep the colour details for future repairs
  • Don’t let trades patch coloured joints with a random sealant

Colours can soften with light and weathering. That is normal for exposed sealant, and a reseal brings it back.

Make sure every contractor knows which sealant and colour are on the building file. It stops mismatched repairs creeping in.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Repairing damaged frames or cladding
  • Custom-mixed sealant colours
  • Materials with mixed tones that defy a single match

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.

What we seal

  • Office fit-out finishes
  • Hotel bathrooms and public areas
  • Shop-fit joinery and counters
  • Powder-coated and anodised frames
  • Cladding panels
  • Natural stone and brick

What Purley on Thames’s businesses ask us to seal

The 3 miles around Purley on Thames take in at least three named trading estates, business parks or retail parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies. Central London is about 41 miles from Purley on Thames. Business parks and retail centres are common around the capital’s motorway corridors. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

Shopping centres and retail parks such as Reading Retail Park, 2 miles south-east of Purley on Thames, see a steady turnover of shop fits, each leaving joints where colour and finish matter.

On a business park such as Oxford Road Business Park, which lies south-east of Purley on Thames, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few hours or a phased programme, depending on joint lengths and how many colours are involved, and we clear our waste as we work. Several jobs near Purley on Thames can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. Photos or drawings show us the finishes and joints.
  2. We send the closest colours from the product’s range.
  3. The programme and access are agreed, including any phasing.
  4. Joints are prepared, primed where specified and backed.
