Mastic sealing in Oldbury
Managing agents and housing associations usually need paperwork before anyone starts. 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, with public liability insurance. The enquiries we see most involve damp patches beside frames and damaged joints in communal entrances and corridors, on communal entrances and stairwells, balcony and threshold joints and shopfronts below residential blocks. Most enquiries from Oldbury 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.
Around smaller places like Oldbury, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Looking after buildings in and around Oldbury
Oldbury is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Oldbury is about 22 miles from central London. Within reach of London, blocks run by agents and associations are common around stations.
For a school such as Ightham Primary School, perimeter mastic on windows and doors is a holiday job. Buildings close to stations like Borough Green & Wrotham station (to the north-east of Oldbury) are often flats over shops, with frame mastic to keep sound.
Oldbury is about 4 miles east of Sevenoaks, in Kent. Oldbury sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Oldbury is one of 931 places in Kent on our list for mastic joints. Sites around London have their own page, about 22 miles away.
Business premises anywhere in TN15 are within our area for mastic joints. For a building on Oldbury Lane, Spring Lane and Sevenoaks Road or nearby, we can quote for mastic joints. Just outside Oldbury, we also work in Ightham (1 mile south), Styants Bottom (1 mile west), Ivy Hatch (1 mile south), Sheet Hill (1 mile south-east) and Stone Street (1 mile south-west). Nearby towns on our patch include Maidstone (11 miles east), Dartford (11 miles north), Sevenoaks (4 miles west), Royal Tunbridge Wells (10 miles south), Gravesend (11 miles north-east) and Tonbridge (6 miles south).
Around Oldbury
Locally, jobs take us to sites close to The Old House, Ivy Hatch Nature Reserve and Wrotham School. For rail, the closest station is Borough Green & Wrotham station, about 1.4 miles north-east. Nearby you will also find Beechin Wood Archery Museum (2.4 miles east) and Ightham Court (0.8 miles north-east).
What we’re called out for in Oldbury
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 splits as the building moves.
It’s worth sending us details if you spot any of the following:
- Brittle perimeter mastic across a building
- No planned programme for sealant
- Draught complaints from residents or tenants
- Patchy repairs in mismatched sealant
If you are responsible for a building such as Church of St Peter, frame and door mastic needs the same attention as any other property.
What to look for in a quote
- Proof of insurance
- How joint depth will be controlled
- Do they follow the manufacturer’s priming guidance?
- Their pre-qualification and accreditations
Leave it or put it right?
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. Older rural buildings around Oldbury move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Your questions answered
Can you quote for a block close to Borough Green & Wrotham station?
Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Oldbury off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
How long will the new sealant last?
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.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Glazing that needs replacing
- Leaks from above rather than through a joint
If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think.
Joints and surfaces we work on
- Balcony and threshold joints
- External wall and movement joints

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Log resealing dates block by block
- Look at the sunniest and most exposed elevations first
- Keep bins and bikes away from communal door frames
- Encourage occupiers to report problems at frames
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
