Aftercare for building managers
A few simple habits keep the new joints working:
- Make mastic part of routine maintenance checks
- Log resealing dates block by block
- List the paperwork your organisation requires when you send details
- Encourage occupiers to report problems at frames
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
About our mastic sealing in Dane Hill
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Dane Hill carry our 12-month guarantee. The enquiries we see most involve a mix of products and colours from past repairs and cracked, hardened mastic round windows on a block, on balcony and threshold joints, window and door perimeters on blocks and external wall and movement joints. A single leaking joint is often how a building in Dane Hill first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners and agents with buildings around smaller places such as Dane Hill tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Why deal with it now?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Halls, stores and units around places like Dane Hill may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Dane Hill: questions and answers
Is Dane Hill off your patch?
No. Places such as Dane Hill are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Will you take on work at estates like Hatch End Old Industrial Estate, close to Dane Hill?
Yes. We cover Dane Hill and the area around it, including industrial estates, business parks and retail parks such as Hatch End Old Industrial Estate. Photos and a short description are enough for a first look.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you send RAMS and CSCS details before starting?
Let us know your requirements: 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.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

For managing agents and facilities managers
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Redoing a failed joint typically costs more than getting it right at the outset, 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.
Diagnose, treat, sign off
