Your questions answered
Will you take on work at estates like Waldegraves Business Park, close to West Mersea?
Yes, sites like Waldegraves Business Park are within our area, along with the rest of West Mersea. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Does a coastal location like West Mersea affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you replace windows or glass?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, such as perimeter joints where frames meet the structure.
Facade sealing in West Mersea, done properly
External joints face UV, rain, temperature swings and building movement all year. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on window and door perimeters, cladding panel joints and perimeter joints where frames meet the structure, and the failures we’re asked to look at most are draughts around frames and panels and sealant pulling away from frames or panels. Most enquiries from West Mersea 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.
In a smaller place such as West Mersea, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Our process
Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For a site in West Mersea, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- 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.
What we need from you
- Flag any permit to work we’ll need
- Let building users know which areas are affected
- Move anything stored against the joints

Advice
Contractors’ notes for West Mersea
West Mersea lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
When units on a site such as Waldegraves Business Park, 1.1 miles to the east of West Mersea, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Common problems we fix in West Mersea
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.
Common reasons buildings call us in:
- Facade joints cracked through the middle
- Weathered joints at frame-to-structure perimeters
- Gaps between rainscreen or cladding panels
- Previous reseals run over old sealant
School extensions, at buildings such as Mersea Island School, usually run to the summer holidays, mastic included.

- Will CSCS-carded applicators be on site?

What else we do in West Mersea
Looking after the joints
A few simple habits keep the new joints working:
- Share access with other external trades
- Don’t wait for a second leak before calling
- Ask about asbestos in pre-2000 mastic
- Brief window cleaners about newly sealed joints
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Why act early in West Mersea
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
