Block-wide mastic in Clayhall
Clayhall is within about 1 mile of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. There are six care or nursing homes within about 2 miles of Clayhall. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Buildings close to stations like Portsmouth Harbour station (to the north-east of Clayhall) are often flats over shops, with frame mastic to keep sound. Landlords with units on estates such as QinetiQ Haslar Marine Technology Park, less than half a mile to the north-east of Clayhall, can bring frame, door and external mastic across several units into one programme. If you are responsible for a building such as St Francis, frame and door mastic needs the same attention as any other property.

A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. We work on external wall and movement joints, communal entrances and stairwells and communal kitchens and washrooms, and the usual reasons a site gets in touch are leaks at window and door perimeters and open joints in brickwork or panels.

Clayhall: questions and answers
Is QinetiQ Haslar Marine Technology Park, near Clayhall, within your area?
Yes. Our area takes in Clayhall and its surroundings, with estates and business parks such as QinetiQ Haslar Marine Technology Park included. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
Is a smaller place like Clayhall outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
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 are CHAS accredited and a Constructionline member.
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
For managing agents and facilities managers
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Why deal with it now?
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work with less control over timing. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area.

- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Preparing the site
- Point out any areas we must not close

Request a quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Advice
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Asbestos-containing sealant, which we don’t remove
- Water coming in from the roof or rainwater goods
- Failed window or door frames, which need a window contractor
If you are not sure, just ring 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Balcony and threshold joints
Quoting for work in Clayhall
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Site requirements such as inductions and permits
- Working within restricted access windows
- How accessible the joints are
- The product specified
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- Drawings or a marked-up plan, if available
- Your programme or deadline
- Anything awkward about access or site hours
- Specification clauses that apply
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email us.
