What we’re called out for in World's End
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone and the repair soon fails.
Typical triggers for a call:
- Old repairs sealed over failed mastic
- Draught complaints from residents or tenants
- The same joint failures repeated across a portfolio
- Complaints coming in block by block
Churches, halls and community buildings such as St Andrew's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What your quote should include
- Health and safety accreditation such as CHAS
- How the existing material will be dealt with
- What site paperwork they can supply
- How long is the guarantee, and what does it include?
Mastic sealing in World's End
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints, and the usual reasons a site gets in touch are a mix of products and colours from past repairs and repeated reactive repairs to the same buildings. Whoever orders the work in World's End, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Older buildings and conversions around places like World's End mix old masonry with newer frames. The mastic there needs to suit both surfaces.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Your questions answered
Do you cover business parks and estates near World's End, such as Ashwyn Business Centre?
Yes, sites like Ashwyn Business Centre are within our area, along with the rest of World's End. A few photographs and the unit address let us price the work.
Is World's End off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
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 inspection is the best way to catch problems early.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
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.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What else we do in World's End
What the job involves on each surface
Planned maintenance
Resealing can be scheduled alongside other planned works, building by building.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. We plan around the site hours and access windows you give us.
What sets the cost
Before we quote, we look at:
- Which sealant the job calls for
- Location, for remote and island sites
- Any access equipment needed
- Site requirements such as inductions and permits
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Any specification or named product
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- How the joints are reached, and at what height
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or send photos by email if you’d rather talk the job through.
Mastic sealing in World's End: the local picture
Rainfall across the South East, World's End included, is lower than in many parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Two care or nursing homes sit less than 2 miles from World's End. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Property owners at sites such as Ashwyn Business Centre, 0.7 miles to the west of World's End, can have mastic renewed between lettings. If your remit includes a building such as Manor Field Primary School, frame and door mastic can be programmed for the holidays.

Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Plan resealing building by building rather than complaint by complaint
- Prioritise elevations facing the weather
- Keep a record of when each building was resealed
- Have the asbestos survey to hand for older buildings
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. For a site in World's End, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Before we start on site
- Flag any permit to work we will need
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
