Mastic sealing in Courtsend
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. Site teams most often ask us about communal area joints that look neglected and patchy repairs in mismatched sealant, on window and door perimeters on blocks, balcony and threshold joints and communal kitchens and washrooms. One point of contact handles commercial sealant work in Courtsend from the first photographs to the final walk-round, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Courtsend tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Leave it or put it right?
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Converted and older buildings near places like Courtsend tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Group repairs into a planned programme
- Track which buildings were done and when
- Have the asbestos survey to hand for older buildings
- Make it easy for occupiers to report draughts
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, 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. Rural sites near Courtsend may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Make sure the joints can be reached
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements

Advice
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Phasing around occupants
- Access and working height
- Induction, permit and paperwork requirements
- The size and state of each joint
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
To price the job accurately, we need to understand the site. Useful things to include:
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work
- The product your specification calls for
- Access details, including height
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or send photos by email.
What the job involves on each surface
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Broken glass or failed sealed units
- Failed window or door frames, which need a window contractor
- Masonry that has broken away beside the joint
If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Communal entrances and stairwells
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
Looking after buildings in and around Courtsend
With the shore within about 1 mile, Courtsend counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Courtsend is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
For a building around Courtsend, a look at every elevation first shows which joints need renewing now and which can wait. Owners near Courtsend can renew frame and external mastic block by block on one programme.

What else we do in Courtsend
Courtsend: questions and answers
Does a coastal location like Courtsend affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can one quote cover a number of our buildings near Courtsend?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Will residents or tenants be disturbed?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
