How we handle facade sealing in Crews Hill
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on perimeter joints where frames meet the structure, coping and flashing joints and stone and brick facade joints, and what we’re called in for most is old perimeter mastic that has dried out and new sealant peeling off old mastic. Whoever orders the work in Crews Hill, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Construction in a London area such as Crews Hill means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Whoever the client is, the cover is the same: 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.

Sites and facades in and around Crews Hill
The ULEZ covers the whole of Greater London, Crews Hill included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
With historic properties like Forty Hall (to the south-east of Crews Hill) in the area, refurbishment work often meets old masonry that needs compatible sealants. On a healthcare site such as Chase Farm Hospital, which lies south of Crews Hill, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

FAQs: Crews Hill
Will you take on work at estates like Sopers Road Industrial Estate, close to Crews Hill?
Yes. We cover Crews Hill and the area around it, including industrial estates, business parks and retail parks such as Sopers Road Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Can you work on a hospital site such as Chase Farm Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Do you cover Crews Hill?
Yes. We cover Crews Hill. To discuss a job, call the office on 01277 525 020 or send photos by email.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Commercial clients in Crews Hill
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What we’re called out for in Crews Hill
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.
What tends to prompt an enquiry:
- Unsightly perimeter sealant on a visible elevation
- Weathered joints at frame-to-structure perimeters
- New sealant peeling off old mastic
- Draughts around frames and panels
When a college such as Capel Manor College, 1.9 miles east of Crews Hill, builds or refurbishes, the mastic package usually has to fit around students and staff.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- What the guarantee covers, and for how long
- Their approach to joint depth and backing
- Proof of insurance
Why deal with it now?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why us?
- Failed material removed, not covered up
- Colour options checked against the specified product
- CSCS-carded applicators
- Commercial sealant work since 2005

How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The site’s rules and procedures
- Access and working height
- Distance, for remote addresses
- How much there is to seal
A quote for facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
What we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- The product your specification calls for
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- When you need the work done
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Our process
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. In Crews Hill, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with photos, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Tell staff and tenants when we’ll be in
- Share your working hours and any access restrictions
