How we handle mastic sealing in Hartlip
Managing agents and housing associations usually need paperwork before anyone starts. 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’re dealing with repeated reactive repairs to the same buildings and estate-wide sealant that is simply worn out, we can put it right. For commercial sealant work in Hartlip, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around smaller places like Hartlip, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
A 12-month guarantee applies to all our work in Kent. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we will come back to it.

Should maintenance staff do it?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Common questions from Hartlip clients
Does your area include sites such as Newington Industrial Estate, near Hartlip?
Yes. Our area takes in Hartlip and its surroundings, with estates and business parks such as Newington Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is Hartlip off your patch?
Not at all. Hartlip is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
How do you reach windows on upper floors?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Can you reseal a whole block or estate?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
When it isn’t the sealant
Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:
- Water coming in from the roof or rainwater goods
- Masonry that has broken away beside the joint
- Leaks through the frame itself rather than the perimeter
If you are not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- Communal entrances and stairwells
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Include mastic in your cyclical inspections
- Track which buildings were done and when
- Share the asbestos register when you send details
- Group repairs into a planned programme
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Hartlip can be grouped with others nearby. A fixed quote is given before anything starts.

Signs you need mastic sealing in Hartlip
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Site and facilities staff are often the first to spot these:
- Worn sealant at communal door frames
- Brittle perimeter mastic across a building
- Damp patches beside frames
- Estate-wide sealant that is simply worn out
If you’re responsible for a building such as Church of St Michael, frame and door mastic needs the same attention as any other property.
