How we handle mastic sealing in Howwood
Across Howwood and the rest of Renfrewshire, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. Site teams most often ask us about mastic failing across several blocks on an estate and failed external movement joints, on communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Howwood it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Howwood, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Howwood: questions and answers
Is a smaller place like Howwood outside your area?
No. Small places get the same service as large ones. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Can you quote for mastic across several buildings in and around Howwood?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we’ll give a fixed quote.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Howwood is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first.

Surface by surface
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
When to call us in Howwood
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.
These are often picked up first by site or facilities staff:
- Draught complaints from residents or tenants
- Old repairs sealed over failed mastic
- Failed external movement joints
- Window mastic that has split and shrunk
Buildings close to stations like Howwood station (less than half a mile west of Howwood) are often flats over shops, with frame mastic to keep sound.
Questions to ask before you book
- Their approach to joint depth and backing
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
- What level of public liability insurance do they hold?
