Construction mastic in Crow, done properly
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. We work on floor and skirting junctions, sanitary and kitchen joints and brick and block movement joints, and the failures we’re asked to look at most are failed sealant in an existing building being refurbished and frame perimeters left unsealed or poorly sealed. Most enquiries from Crow start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in and around smaller places such as Crow is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

How a job runs
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Crow may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready

Questions about Crow
Is a hospital such as St Leonard's Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is Crow too far out for you?
No. Places such as Crow are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you do internal caulk as well as external mastic?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
Can you work plot by plot or floor by floor?
We work to your programme. Share the release dates and we’ll match our work to them so sealing follows the trades.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
What the job involves on each surface
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line and reduces snags.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
Honest limits
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Oversized gaps that need packing or adjustment by others
If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Facades, frames and programmes in Crow
Crow has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Rainfall across the South East, Crow included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
School extensions, at buildings such as Ringwood Junior School, typically run to the summer holidays, mastic included. Historic houses such as Avon Tyrrell House, 2.4 miles to the south-east of Crow, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors at a college like Sheiling College (2.4 miles west of Crow), perimeters and internal sealant are timed for the holidays.

Quoting for work in Crow
These are the things that shape the price:

Pricing mastic packages depends on quantities, condition and access, and any specification that applies. Call for a quote.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- The product your specification calls for
- When you need the work done
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
