About our mastic sealing in Havant
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. Site teams most often ask us about water getting in round frames after rain and failed external movement joints, on window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks. Looking for mastic applicators who cover Havant? We have been sealing commercial buildings since 2005.
In Havant, as in most towns, a block may have frames from several eras, which leaves perimeter mastic of very different ages. Looking at the whole building first shows what needs doing now and what can wait.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why it’s worth doing now in Havant
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. In Havant, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What we are called out for in Havant
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Look out for the following:
- Damp patches beside frames
- Worn sealant at communal door frames
- Window mastic that has split and shrunk
- Complaints coming in block by block
Buildings close to stations like Havant station (0.6 miles south of Havant) are often flats over shops, with frame mastic to keep sound.
Before you book anyone
- How the existing material will be dealt with
- Health and safety accreditation such as CHAS
- Will RAMS and insurance details be available?
- Proof of insurance
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Most work in Havant is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Share your contractor requirements early
- Look at the sunniest and most exposed elevations first
- Have the asbestos survey to hand for older buildings
- Avoid piecemeal callouts where you can
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks through the frame itself rather than the perimeter
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
