Commercial clients in Hawthorn
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Mastic sealing in Hawthorn, done properly
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. The enquiries we see most involve a mix of products and colours from past repairs and open joints in brickwork or panels, on external wall and movement joints, balcony and threshold joints and window and door perimeters on blocks. Whoever orders the work in Hawthorn, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Hawthorn, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

After the work
A few simple habits keep the new joints working:
- Plan resealing building by building rather than complaint by complaint
- Include mastic in your cyclical inspections
- Track which buildings were done and when
- Share your contractor requirements early
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Do you need mastic sealing in Hawthorn?
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
Look out for the following:
- Communal area joints that look neglected
- Failed external movement joints
- The same joint failures repeated across a portfolio
- Draughts at frames across a block
Buildings close to stations like Herne Bay station, 2.4 miles west of Hawthorn, are often flats over shops, with frame mastic to keep sound.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Who will actually carry out the work
- Their public liability cover
- Is the sealant right for the movement and the substrate?
On site: what to expect
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Rural sites near Hawthorn may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Make sure the joints can be reached

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Common questions from Hawthorn clients
Is Hawthorn off your patch?
No. Places such as Hawthorn 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.
Will you take on work at estates like Eddington Business Park, close to Hawthorn?
Yes. Estates, retail parks and business parks around Hawthorn, Eddington Business Park among them, are all within reach. Photos and a short description are enough for a first look.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Can you send RAMS and CSCS details before starting?
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.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
