About our mastic sealing in Oakhanger
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. The enquiries we see most involve the same joint failures repeated across a portfolio and failed external movement joints, on external wall and movement joints, shopfronts below residential blocks and balcony and threshold joints. Facilities teams, main contractors and managing agents in Oakhanger tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Oakhanger, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Questions about Oakhanger
Is a smaller place like Oakhanger outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Is Southlands Industrial Park, near Oakhanger, within your area?
Yes. Estates, retail parks and business parks around Oakhanger, Southlands Industrial Park among them, are all within reach. A few photos and the unit address let us price the work.
How long does a job like this take?
It depends on the scope, but the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Common problems we fix in Oakhanger
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
Any of the following is a good reason to get the joints checked over:
- Patchy repairs in mismatched sealant
- Damp patches beside frames
- Worn sealant at communal door frames
- Mastic failing across several blocks on an estate
Older community buildings, St Mary Magdalene's Church among them, often have frames of mixed ages whose mastic varies.
Before you book anyone
- How the joint faces will be prepared and primed
- Is the sealant right for the movement and the substrate?
- Who will actually carry out the work
- Are they CHAS accredited or on Constructionline?
Owners, agents and contractors
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Why it’s worth doing now in Oakhanger
Sealing over failed mastic looks tidy for a while. It doesn’t bond and normally fails within a short time. Full removal and proper preparation is what lasts. Around Oakhanger, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
A quote for mastic joints depends on how many there are, their condition and the access. Call for a quote.

Maintenance after handover
A few simple habits keep the new joints working:
- Include mastic in your cyclical inspections
- Share the asbestos register when you send details
- Start inspections with the most exposed faces
- Mention RAMS, insurance or CSCS requirements up front
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Oakhanger need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Preparing the site
- Let building users know which areas are affected
- Agree which areas must stay open
- Make sure the joints can be reached
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Planned mastic for Oakhanger portfolios
Oakhanger is about 44 miles from central London. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Site managers at schools like Mill Chase Academy can fit frame mastic into the summer works. If you own or manage units on a site such as Southlands Industrial Park, which lies south of Oakhanger, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
