Mastic sealing in Aperfield, done properly
Across Aperfield and the rest of Greater London, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints, and the failures we’re asked to look at most are the same joint failures repeated across a portfolio and complaints coming in block by block. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Aperfield, preparation and product choice get the time they need.
In a London area such as Aperfield, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time, which is why block-wide programmes make sense.
Every job we finish is backed by a 12-month workmanship guarantee, in Aperfield as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Should maintenance staff do it?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Share the asbestos register when you send details
- Check sealant joints during planned building inspections
- Reduce knocks to communal area joints
- Look at the sunniest and most exposed elevations first
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Asbestos-containing sealant, which we don’t remove
- Leaks through the frame itself rather than the perimeter
- Leaks from above rather than through a joint
Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly.

What affects the price in Aperfield
We price every job individually. The main factors are:
- Backing rod, priming and other preparation
- How accessible the joints are
- How much there is to seal
- The product specified
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

It doesn’t need to be a full survey. These details are enough to start:

Your questions answered
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.
Is Biggin Hill Airport Trading Estate, near Aperfield, within your area?
Yes. Our area takes in Aperfield and its surroundings, with estates and business parks such as Biggin Hill Airport Trading Estate included. A few photos and the unit address let us price the work.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
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 will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
