Mastic sealing for Broomfield sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Keeping the joints sound
A few simple habits keep the new joints working:
- Encourage occupiers to report problems at frames
- Avoid piecemeal callouts where you can
- Start inspections with the most exposed faces
- Share your contractor requirements early
Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
About our mastic sealing in Broomfield
Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. If you are dealing with patchy repairs in mismatched sealant and worn sealant at communal door frames, we can put it right. Most enquiries from Broomfield start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Broomfield, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
FAQs: Broomfield
Is Broomfield off your patch?
Not at all. Broomfield is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you work at a site such as Roebuck Business Park, by Broomfield?
Yes. Estates, retail parks and business parks around Broomfield, Roebuck Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

What we’re called out for in Broomfield
Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant, so these repairs rarely last.
These are often picked up first by site or facilities staff:
- Patchy repairs in mismatched sealant
- Cracked, hardened mastic round windows on a block
- Open joints in brickwork or panels
- Occupiers reporting cold air round windows
Buildings close to stations like Hollingbourne station, 1.6 miles to the north of Broomfield, are often flats over shops, with frame mastic to keep sound.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Are they CHAS accredited or on Constructionline?
- Will CSCS-carded applicators be on site?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?

Frames, entrances and external joints in Broomfield
Broomfield sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Broomfield lies roughly 36 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
If you own or manage units on a site such as Roebuck Business Park (1.6 miles east of Broomfield), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If you manage student housing near a university such as Canterbury Christ Church University, which lies north-east of Broomfield, the summer turnaround is the time for mastic.
