Mastic sealing in Holywell, done properly
Across Holywell and the rest of East Sussex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. Most enquiries involve the same joint failures repeated across a portfolio and window mastic that has split and shrunk, on communal kitchens and washrooms, external wall and movement joints and window and door perimeters on blocks. Most enquiries from Holywell start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Owners with buildings around smaller places like Holywell often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.
Our workmanship is guaranteed for 12 months, in Holywell as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Holywell
Can you work at a site such as Courtlands Road Industrial Estate, by Holywell?
Yes. Estates, retail parks and business parks around Holywell, Courtlands Road Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
Is Holywell 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. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

External movement joints
Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. We plan around the site hours and access windows you give us.
On site: what to expect
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Holywell is a clear list of what needs doing, so send photos of each area. A fixed quote follows.
- We inspect the joints, building by building, and record what has failed and why.

- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.

Related advice
Why deal with it now?
A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Frames, entrances and external joints in Holywell
Holywell sits close to the coast, within about 1 mile. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Holywell is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you own or manage units on a site such as Courtlands Road Industrial Estate, 1.8 miles to the north of Holywell, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If you are responsible for a building such as St John the Evangelist, frame and door mastic needs the same attention as any other property. Schools and community buildings such as St John's Meads Church of England Primary School need frame and external mastic kept sound like any building.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
- Glazing that needs replacing
If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think.

How the quote is worked out
These are the things that shape the price:
- The product specified
- Phasing around occupants
- Any access equipment needed
- How much existing material needs removing
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
We can often quote from photos and a few details. It helps to include:
- Access details, including height
- Your programme or deadline
- The asbestos register, for older buildings
- The site address and postcode
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or use the quote form.
After the work
Regular inspection catches problems early. Specifically:
- Start inspections with the most exposed faces
- Log resealing dates block by block
- Avoid piecemeal callouts where you can
- Make it easy for occupiers to report draughts
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
