What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Masonry that has broken away beside the joint
- Asbestos-containing sealant, which we don’t remove
- Leaks from above rather than through a joint
If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.

How we handle mastic sealing in Snagshall
Managing agents and housing associations normally need paperwork before anyone starts. For documents, 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. If you have window mastic that has split and shrunk and patchy repairs in mismatched sealant, we can put it right. Looking for mastic applicators who cover Snagshall? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around smaller places like Snagshall, 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. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

General trades versus a specialist
Some joints are best left to specialists: for instance 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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
For owners and agents in Snagshall
Snagshall is about 45 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
If you look after a block within reach of Robertsbridge station, which lies west of Snagshall, frame and balcony mastic can be renewed on one programme. If you are responsible for a building such as The Parish Church of St James, frame and door mastic needs the same attention as any other property.

Your questions answered
Is Quarry Farm Business Centre, near Snagshall, within your area?
Yes, sites like Quarry Farm Business Centre are within our area, along with the rest of Snagshall. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Snagshall outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally 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’ll give you a timescale with the quote.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
What paperwork can you provide?
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.
Do you do block-wide mastic programmes?
We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
Our process
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Snagshall can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.

Before you send an enquiry
The more we know, the firmer the quote. When you get in touch, include:
- The product your specification calls for
- Photos of the joints, close up and from further back
- When you need the work done
- What the building is and how it’s used

When to call us in Snagshall
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.
Common reasons buildings call us in:
- Draughts at frames across a block
- Failed external movement joints
- Brittle perimeter mastic across a building
- Damaged joints in communal entrances and corridors
Schools and community buildings such as Bodiam Church of England Primary School need frame and external mastic kept sound like any building.
