About our mastic sealing in Tower Hill
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Most enquiries involve estate-wide sealant that is simply worn out and draughts at frames across a block, across external wall and movement joints, communal kitchens and washrooms and shopfronts below residential blocks. Most enquiries from Tower Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For owners with a single building near Tower Hill, we plan to finish in one visit where possible. Send photographs of the frames and joints and we’ll give a fixed quote.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Building owners, agents and FMs in Tower Hill
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Tower Hill can form part of a wider programme across Hertfordshire.
How the job changes by surface
Communal areas
Low-level communal joints get damaged more than most, so they often need renewing sooner.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Tower Hill can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- 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

Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Why deal with it now?
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. Converted and older buildings near places like Tower Hill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, since every building and every scope is different. Call for a quote.

Planned mastic for Tower Hill portfolios
Central London is about 23 miles from Tower Hill. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Tower Hill is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
Older community buildings, Church of St Paul among them, often have frames of mixed ages whose mastic varies. For owners of several units at places like Chancerygate Business Centre, which lies north-east of Tower Hill, one programme can deal with frame and external mastic across the lot. If your remit includes a building such as Kings Langley School, frame and door mastic can be programmed for the holidays.

Questions about Tower Hill
Is Tower Hill 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 quote for a block close to Hemel Hempstead station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
How do you handle work on occupied blocks?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Which sealant will you use?
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.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How long does a typical visit take?
It depends on the scope, though a typical visit 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.
