About our construction mastic in Broughton
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Broughton, send drawings and the specification through our quote form. Site teams most often ask us about early adhesion failures on new external joints and sanitary sealant damaged by following trades, across brick and block movement joints, internal decorators’ caulk and sanitary and kitchen joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Broughton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like Broughton, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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 easy to get wrong without experience.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Joint design decisions that belong to the architect or engineer
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you’re not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer.
What we seal
- Cladding and panel joints

Sites and facades in and around Broughton
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Broughton is about 69 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
School extensions, at buildings such as Broughton Primary School, normally run to the summer holidays, mastic included. With historic properties like Mottisfont Abbey (to the south of Broughton) in the area, refurbishment work often meets old masonry that needs compatible sealants.
Broughton is about 8 miles north-west of Romsey, in Hampshire. Anywhere in SO20, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Questions we are asked in Broughton
Which documents can you supply for work in Broughton?
RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can you keep pace with our programme in Broughton?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Are you CHAS accredited?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Why act early in Broughton
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility. One visit to deal with every failing joint makes more sense than several trips to a place like Broughton, rather than one at a time. Send photographs of each area and we will quote for the lot.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Snagging before handover
Snags normally come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
