Should maintenance staff do it?
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
Surfaces we seal
- Window and door perimeters on blocks

Mastic sealing in Denvilles: the local picture
Denvilles is within about 1 mile of the coast. On buildings near the shore, the side facing the weather typically needs its mastic renewed first; plan inspections around that. Denvilles is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
If you own or manage units on a site such as Central Retail Park, 0.9 miles to the west of Denvilles, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Historic properties like Warblington Castle, 0.7 miles south of Denvilles, show the age of some local stock, where frame mastic must suit soft brick or stone.
Denvilles is about 1 mile south-east of Havant, in Hampshire. Businesses, contractors and managing agents in Denvilles use us for work on mastic joints, as part of our coverage of Hampshire.

How a job runs

Questions about Denvilles
Will you take on work at estates like Central Retail Park, close to Denvilles?
Yes, sites like Central Retail Park are within our area, along with the rest of Denvilles. Send details of the unit and the work through our quote form for a quick quote.
Is Denvilles too small for you to travel to?
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.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
When to call us in Denvilles
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
It’s worth sending us details if you spot any of the following:
- No planned programme for sealant
- Failed external movement joints
- Communal area joints that look neglected
- A mix of products and colours from past repairs
Buildings close to stations like Warblington station, less than half a mile south-west of Denvilles, are often flats over shops, with frame mastic to keep sound.
What to look for in a quote
- What site paperwork they can supply
- Whether their applicators hold CSCS cards
- How the existing material will be dealt with
- Can the work be phased to keep areas open?
What happens if it’s left?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. 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.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
