Construction mastic in Strood, done properly
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Strood, send drawings and the specification through our quote form. If you are dealing with sanitary sealant damaged by following trades and a long mastic snag list close to completion, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Strood it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like Strood, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Strood, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Ask cleaners to use soft cloths around fresh sealant
- Don’t force external sealing on a damp or frosty day
- Bring the mastic contractor in after the last trades are through
- Keep finished joints away from paint, plaster and scrapers
Record which products went where in the handover file. That helps the building owner maintain the joints later. We can confirm the handover information you need when we quote.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
FAQs: Strood
Is Strood too small for you to travel to?
No. Places such as Strood are covered as much as the big 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 Business Park, by Strood?
Yes. We cover Strood and the area around it, including industrial estates, business parks and retail parks such as Business Park. Send details of the unit and the work through our quote form for a quick quote.
Is the mastic package guaranteed?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Can you fit around our programme?
We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start and adjusted as things change.
Site staff or a sealant specialist?
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, which is what makes a joint last.
Certain joints really need a specialist: 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.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. For a building around Strood, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- Let us know about inductions and permits
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000

Advice
Mastic packages on Strood sites
Strood is about 44 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. A 2-mile radius around Strood takes in several hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
For contractors at a school such as Rolvenden Primary School, sealing has to be finished before term starts. New wings at hospitals like West View Hospital (to the east of Strood) bring long runs of window and panel joints to seal. With historic properties like Smallhythe Place (2.6 miles south-east of Strood) in the area, refurbishment work often meets old masonry that needs compatible sealants.
