How we handle construction mastic in Silver Street
On a new build, the mastic package is one of the last trades through each area. We work as a mastic subcontractor to main contractors and developers. The enquiries we see most involve external joints sealed in damp or cold conditions that are now failing and a mastic package split between trades with no clear owner, across internal decorators’ caulk, sanitary and kitchen joints and window and door perimeters. Searching for sealant specialists in Silver Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Conversions of older rural buildings near smaller places such as Silver Street bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

After the work
After handover, a little attention goes a long way:
- Bring the mastic contractor in after the last trades are through
- Get the mastic subcontractor involved early in the programme
- Brief following trades on areas that have been sealed
- Use the product the specification names
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. We can confirm the handover information you need when we quote.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.
Questions we’re asked in Silver Street
Is Silver Street too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you work at a site such as Kent Science Park, by Silver Street?
Yes, sites like Kent Science Park are within our area, along with the rest of Silver Street. Photos and a short description are enough for a first look.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
Will you stick to the specified products?
We follow the specified sealant and flag anything that doesn’t look right for the joint. Product standards such as BS EN 15651 are often named in specifications.
Who decides which product is used?
A specification, where there is one, decides it. 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.
Why deal with it now?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. If the frame is life-expired, we will tell you. For buildings around smaller places like Silver Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Silver Street may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.

Advice
General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What we are called out for in Silver Street
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Clients usually get in touch after noticing one or more of the following:
- Sealant knocked or painted over by other trades
- Existing joints on a refurb that need cutting out and resealing
- Missed perimeter joints on a new elevation
- Different trades sealing to different standards
School extensions, at buildings such as Bredgar Church of England Primary School, typically run to the summer holidays, mastic included.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Proof of insurance
- How the joint faces will be prepared and primed
- How they’ll work around occupants
What affects the price in Silver Street
A fixed quote reflects the actual work. It allows for:
- Travel to remote or island sites
- Phasing around occupants
- Backing rod, priming and other preparation
- Access and working height
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- The postcode of the building
- Whether an asbestos survey exists
- Your programme or deadline
- A wide shot and a close-up of the area

Mastic packages on Silver Street sites

Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 36 miles from central London, Silver Street is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
