Questions about Houston

Is a smaller place like Houston outside your area?

No. Small places get the same service as large ones. We work across every Scottish council area. Good photographs up front let us bring everything on the first visit.

Can you work at a site such as Mossedge Industrial Estate, by Houston?

Yes, sites like Mossedge Industrial Estate are within our area, along with the rest of Houston. Send details of the unit and the work through our quote form for a quick quote.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Are you CHAS accredited and on Constructionline?

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

Can coloured sealant be used in washrooms and kitchens?

Yes, in many cases. Hotel bathrooms, washrooms and kitchens often use coloured sanitary silicone to suit tiles or stone.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use.

About our coloured sealant in Houston

In retail, hospitality and office fit-outs, joints are seen close up every day. A mismatched bead can make good joinery look unfinished, even when the seal is sound. The aim is a colour from the product’s range that disappears into the surface. If you have dirty, discoloured joints in public areas and hotel refurbishments with a set colour scheme, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Houston, preparation and product choice get the time they need.

In smaller Scottish places like Houston, commercial buildings are often hotels, pubs, shops, schools, surgeries and farm or estate buildings put to new use. Their kitchens, washrooms and window perimeters all need joints that keep water out.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Travel to smaller Scottish places like Houston is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

What we need from you

  • Share the asbestos register for older buildings
  • Move anything stored against the joints
  • Flag any permit to work we will need

Keeping the joints sound

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Reseal whole runs rather than patching single joints
  • Keep the colour details for future repairs
  • Ask contractors to check the colour before resealing
  • Brief cleaners about newly sealed joints

Use gentle cleaning methods on coloured sealant. Harsh chemicals and scouring can change how the colour looks.

Use one product and colour reference across a building or brand. Consistency makes future work simpler and easier to manage.

Signs you need coloured sealant in Houston

Failed sealant still has to be dealt with, whatever its colour: it can crack, peel or harden with age and movement. We cut out and reseal in the agreed colour.

Things that typically lead to an enquiry:

  • Sealant that no longer suits recoated frames
  • Failed coloured sealant that has split or peeled
  • Weathered sealant that no longer matches
  • Untidy coloured beads with ragged edges

On estates like Mossedge Industrial Estate, which lies south-east of Houston, the office and welfare end of each unit has its own sealant to maintain.

What your quote should include

  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?
  • The terms of the workmanship guarantee
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

How the job changes by surface

Natural stone

Stone has variation, so the aim is a colour that sits naturally against it. A stone-safe neutral-cure product is used in the closest available colour.

Brick and masonry

Vertical movement joints run the full height of many brick walls. The right colour keeps them discreet while the product still suits the movement.

Commercial clients in Houston

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Houston. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Frontages, fit-outs and joints in Houston

Houston is on Scotland’s wetter western side. Frontage work is booked with a few days’ give for the weather. Shopfronts and frames facing the prevailing weather are where failures show first

Shops and cafés around stations like Johnstone station, 2.9 miles to the south-east of Houston, trade from early, so work is timed around them.

Houston is about 3 miles north-west of Johnstone, in Renfrewshire. We cover Houston and the rest of Renfrewshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Houston is one of 23 places in Renfrewshire on our list for colour-matched joints. There’s a separate page for Glasgow, about 11 miles away.

Work on colour-matched joints is covered throughout PA6. We cover commercial and managed buildings on Main Street, St Fillans Drive and South Street. Nearby places we also cover include Crosslee (1 mile south-east), Craigends (1 mile south-east), Bridge of Weir (1 mile south-west), Brookfield (2 miles south-east) and Ranfurly (2 miles south-west). Further afield, our area takes in Paisley (5 miles south-east), Renfrew (6 miles east), Johnstone (3 miles south-east), Erskine (4 miles north-east), Bishopton (3 miles north-east) and Glenburn (5 miles south-east).

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
