Facade sealing in Graveley
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Graveley are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Flag any permit to work we’ll need
- Have the specification and drawings to hand
- Arrange parking or a loading space

Advice
About our facade sealing in Graveley
Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, but not always. If the evidence points away from the sealant, we say so before quoting. Most enquiries involve failed seals around shopfront and entrance frames and leaks at window and door perimeters, on shopfront frames, coping and flashing joints and stone and brick facade joints. Facilities teams, main contractors and managing agents in Graveley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In the countryside around places like Graveley, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. 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’ll confirm with the quote.
Maintenance after handover
A few simple habits keep the new joints working:
- Inspect facade joints on a regular cycle
- Investigate damp beside windows promptly
- Insist on a full cut-out when joints are renewed
- Check the asbestos register before old mastic is disturbed
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal across the elevation.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.

Questions we’re asked in Graveley
Is a hospital such as Lister Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is Monkswood Retail Park, near Graveley, within your area?
Yes. Estates, retail parks and business parks around Graveley, Monkswood Retail Park among them, are all within reach. A few photographs and the unit address let us price the work.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can you find out why a window is leaking?
Yes. We look at the perimeter sealant and tell you whether it has failed. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
When to call us in Graveley
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.
What tends to prompt an enquiry:
- Draughts around frames and panels
- Discoloured or dirty facade joints
- Patch repairs that keep failing
- Cladding panel joints that have opened up
Work at a hotel such as Needham House Hotel (1.4 miles west of Graveley) tends to be programmed around bookings, mastic included.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- Proof of insurance
- How the existing material will be dealt with
- What the guarantee covers, and for how long

General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
