About our mastic sealing in Stedham
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on balcony and threshold joints, window and door perimeters on blocks and external wall and movement joints, and the failures we’re asked to look at most are patchy repairs in mismatched sealant and worn sealant at communal door frames. For commercial sealant work in Stedham, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around smaller places like Stedham, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Share your contractor requirements early
- Ask residents or tenants to report leaks and draughts early
- Protect low-level joints in entrances
- Make mastic part of routine maintenance checks
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
FAQs: Stedham
Is Stedham too far out for you?
No. Places such as Stedham are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you take on block-wide or estate-wide mastic work in Stedham?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we’ll set out a timescale with the quote.
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.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Blocks and managed buildings in Stedham
Stedham sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 46 miles from Stedham. Managed blocks of flats are a big part of commuter-belt property.
If you own or manage units on a site such as Midhurst Business Centre, 1.2 miles south-east of Stedham, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. For a school such as Stedham Primary School, perimeter mastic on windows and doors is a holiday job. Churches, halls and community buildings such as The Parish Church of St James are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
What the job involves on each surface
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Window and door perimeters on blocks
We typically work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Diagnose, treat, sign off
Before we leave any area, 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. For a building around Stedham, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- 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.

- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.

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.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
