Need facade sealing in Newnham?
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.
Precast concrete panels
Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.
About our facade sealing in Newnham
Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around. If you’re dealing with leaks at window and door perimeters and cold air coming in at window perimeters, we can put it right. One point of contact handles commercial sealant work in Newnham from the first photos to the final walk-round, whether it’s one building or several.
Sites around smaller places like Newnham can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Newnham need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Before we start on site
- Confirm the product named in the specification
- Tell staff and tenants when we’ll be in
- Share the asbestos register for older buildings
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Advice
Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Arranging specialist high-level access, which is planned with the client
- Work on the window or framing system itself
- Joints too narrow for the movement they take, which need redesign
If you are not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Newnham: questions and answers
Is a smaller place like Newnham outside your area?
Not at all. Newnham is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Which documents can you supply for work in Newnham?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.
Will you check whether the sealant is causing the leak?
Yes. We check the sealant joints and report what we find as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Do you replace failed glazing units?
No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.
Can you work in cold or wet weather?
Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated throughout the job.

Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
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.
New build and refits around Newnham
Newnham sits in one of the drier corners of the country, the South East.

At about 41 miles from central London, Newnham is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
School extensions, at buildings such as Eastling Primary School, typically run to the summer holidays, mastic included.

What we are called out for in Newnham
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
If one of these sounds familiar, it’s time for a closer look:
- Patch repairs that keep failing
- Weathered facade joints that have lost their grip
- Facade joints cracked through the middle
- Discoloured or dirty facade joints
With historic properties like Belmont House and Gardens (2.2 miles south-east of Newnham) in the area, refurbishment work often meets old masonry that needs compatible sealants.
