When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Construction mastic for commercial buildings in Great Shefford
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. Site teams most often ask us about failed sealant in an existing building being refurbished and sealant knocked or painted over by other trades, on internal decorators’ caulk, floor and skirting junctions and cladding and panel joints. Whoever orders the work in Great Shefford, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Great Shefford bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Work we carry out in West Berkshire comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

Advice
New build and refits around Great Shefford
Rainfall across the South East, Great Shefford included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Great Shefford lies roughly 58 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
For contractors at a school such as Shefford C.E. Primary School, sealing has to be finished before term starts. Sites around Great Shefford get mastic sealed to the drawings and the programme, nothing improvised.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Brief the final clean team to avoid blades near sealant
- Keep product details for future maintenance
- Allow flexibility for external sealing in damp or cold weather
- Keep finished joints away from paint, plaster and scrapers
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.
What happens if it’s left?
Sealing over damaged or contaminated new joints might save a day, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to. We cut out and redo the joint properly. One visit to deal with every failing joint makes more sense than several trips to a place like Great Shefford, rather than one at a time. Photos of every joint help us quote for the whole job.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Common questions from Great Shefford clients
Is Great Shefford too far out for you?
No. Places such as Great Shefford are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What site paperwork comes with a job in Great Shefford?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can the building stay open while you work?
Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Can you work plot by plot or floor by floor?
Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start and adjusted as things change.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

How the job changes by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services so we’ll flag where the detail needs something different. Tell us what records you need and we’ll confirm with the quote.
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified with colours matched to the frame where needed.
