How we handle mastic sealing in Tilbury
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. We work on window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks, and the failures we are asked to look at most are worn sealant at communal door frames and estate-wide sealant that is simply worn out. Facilities teams, main contractors and managing agents in Tilbury tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Older buildings and conversions around places like Tilbury mix old masonry with newer frames. The mastic there needs to suit both surfaces.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Diagnose, treat, sign off
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Tilbury need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Preparing the site
- Point out parking and an unloading spot
- Warn occupants and staff about the work
- Let us know about inductions and permits

For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
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. Keys, access and contacts can be agreed in advance.
FAQs: Tilbury
Is Tilbury off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as London Distribution Park, near Tilbury?
Yes, sites like London Distribution Park are within our area, along with the rest of Tilbury. Send details of the unit and the work through our quote form for a quick quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Leave it or put it right?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. In a smaller place such as Tilbury, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Block-wide mastic in Tilbury
With the shore within about 2 miles, Tilbury counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. At about 20 miles from central London, Tilbury is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property.
Blocks of flats and mixed-use buildings often cluster around stations such as Tilbury Town station (to the west of Tilbury) and their window and balcony mastic tends to age at the same rate across a building. Property owners at sites such as London Distribution Park, 0.6 miles north-west of Tilbury, can have mastic renewed between lettings.

- Frames that are rotten, warped or broken

When to call us in Tilbury
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
Site and facilities staff are often the first to spot these:
- Open joints in brickwork or panels
- Draughts at frames across a block
- Estate-wide sealant that is simply worn out
- Worn sealant at communal door frames
If your remit includes a building such as The Gateway Academy, frame and door mastic can be programmed for the holidays.
Questions to ask before you book
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Health and safety accreditation such as CHAS
- Can the work be phased to keep areas open?
