Mastic sealing for South Hayling sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Joint width, depth and condition
- Removal of failed or old sealant
- How accessible the joints are
- Travel to remote or island sites
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- What the building is and how it’s used
- The product your specification calls for
- The asbestos register, for older buildings
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Mastic sealing in South Hayling, done properly
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on balcony and threshold joints, external wall and movement joints and window and door perimeters on blocks, and what we’re called in for most is worn sealant at communal door frames and the same joint failures repeated across a portfolio. One point of contact handles commercial sealant work in South Hayling from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Older buildings and conversions around places like South Hayling mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, call the office on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Failed window or door frames, which need a window contractor
- Substrate edges that need repairing first
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

FAQs: South Hayling
Do you work in occupied care homes around South Hayling?
Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.
Is South Hayling too far out for you?
No. Small places get the same service as large ones. 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.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. What matters most for a job in South Hayling is a clear list of what needs doing. A fixed quote follows.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Getting the site ready

Planned mastic for South Hayling portfolios
South Hayling sits close to the coast, within about 1 mile. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. The South East is one of the drier parts of the UK. 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.
Older community buildings, St Mary's Church among them, often have frames of mixed ages whose mastic varies. Property owners at sites such as Furniss Business Centre, 0.9 miles to the north-west of South Hayling, can have mastic renewed between lettings.
South Hayling is about 5 miles east of Portsmouth, in Hampshire. Anywhere in PO11, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire.

What else we do in South Hayling
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

- Complaints coming in block by block
