How the job changes by surface
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints finished to throw water off the joint.
Facade sealing in Sunnymead, done properly
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about sealant pulling away from frames or panels and weathered joints at frame-to-structure perimeters, across perimeter joints where frames meet the structure, coping and flashing joints and shopfront frames. A specialist sealant contractor works differently from a general builder: in Sunnymead, that means joint design, primers and backing rod as standard.
For a contractor on a smaller site near Sunnymead, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

What happens if it’s left?
Topping up a failed joint typically buys very little time. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. In a smaller place such as Sunnymead, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Facade sealing in Sunnymead: the local picture
Sunnymead has a good number of 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. At about 54 miles from central London, Sunnymead is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
For a contractor working at a hospital such as John Radcliffe Hospital, 2.5 miles south-east of Sunnymead, perimeter and facade sealing is planned around patients and deliveries. For contractors at a college like Oxford Sixth Form College, which lies south of Sunnymead, perimeters and internal sealant are timed for the holidays. For a contractor at a hotel such as Remont Oxford Hotel, under half a mile to the west of Sunnymead, the mastic often has to be finished before a reopening date.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Several jobs near Sunnymead can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Preparing the site
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space
- Point out any areas we must not close

Your questions answered
Can you work on a hospital site such as John Radcliffe Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does your area include sites such as Jordan Hill Business Park, near Sunnymead?
Yes. We cover Sunnymead and the area around it, including industrial estates, business parks and retail parks such as Jordan Hill Business Park. Photos and a short description are enough for a first look.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can call the office on 01277 525 020 or send details through our quote form to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Can you just add new sealant on top?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
