Coloured sealant in Newtown St Boswells

If you have poorly tooled joints on visible finishes and failed coloured sealant that has split or peeled, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Newtown St Boswells is the same: the right product in a properly prepared joint.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface

Paintable sealants

Overpainting is most common on internal joints with little movement. If the joint needs a product that can’t be painted, we say so.

Natural stone

Sandstone, limestone and granite each have distinct tones. Colour is agreed on site where possible after a sample if needed.

Shops, offices and hotels in and around Newtown St Boswells

Being in the east of Scotland, Newtown St Boswells gets less rain than the west coast. Cold, frosty mornings and condensation on steel and glass can still delay outside work. In winter, outside joints are timed for when surfaces are dry and within the product’s range A 2-mile radius around Newtown St Boswells takes in a number of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme; work is planned so the hotel keeps trading.

Questions we’re asked in Newtown St Boswells

Does your area include sites such as Tweed Horizons Business Centre, near Newtown St Boswells?

Yes, sites like Tweed Horizons Business Centre are within our area, along with the rest of Newtown St Boswells. Photos and a short description are enough for a first look.

Do hotels near Newtown St Boswells have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Will sunlight affect the sealant colour?

Some change over time is normal. Exposure, product and colour all play a part, so no colour stays exactly the same for ever.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Can you match any colour exactly?

No. An exact bespoke match isn’t something we can promise. Sealants come in a wide range of standard colours, and we’ll confirm the colours available for the specified product.

Can staff carry on working while you’re here?

In the majority of cases, yes. We phase the work so most of the building stays in use.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Do you need coloured sealant in Newtown St Boswells?

Failed sealant still has to be dealt with, whatever its colour: it can crack, peel or harden with age and movement. The fix is a full cut-out and a new bead in the right colour.

These are often picked up first by site or facilities staff:

  • Marked sealant in hotel bathrooms
  • Shop fits that need consistent sealant colours across sites
  • Smeared sealant on stone or joinery
  • Colour changes after a rebrand or refit

In hotels such as Dryburgh Abbey Hotel, 1 mile east of Newtown St Boswells, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Before you book anyone

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants
  • Are they CHAS accredited or on Constructionline?
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

Doing it in-house

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.

Certain joints really need a specialist: 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.

Why deal with it now?

Matching new joints to the existing ones is easier when the whole run is done together. Piecemeal repairs over several years tend to drift in colour, so a planned reseal often looks better value. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Newtown St Boswells, a repair visit takes planning, so it’s better to act early.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What you get with us

  • One phone line for London, the South East and Scotland
