Construction mastic across Addiscombe
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Common problems we fix in Addiscombe
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
What tends to prompt an enquiry:
- A long mastic snag list close to completion
- A mastic package split between trades with no clear owner
- Oversized or tapered gaps around new frames
- Internal caulk splitting as the building dries out
Hotels like Croydon Park Hotel (1.2 miles south-west of Addiscombe) rarely close for long, so refurbishment mastic is phased floor by floor.

About our construction mastic in Addiscombe
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. We work on floor and skirting junctions, window and door perimeters and cladding and panel joints, and the usual reasons a site gets in touch are internal caulk splitting as the building dries out and a mastic package split between trades with no clear owner. Most enquiries from Addiscombe 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.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Construction mastic in Addiscombe: the local picture
Plenty of hotels sit less than 2 miles from Addiscombe. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Addiscombe. Delivery slots and scarce storage shape how and when the mastic goes in.
Hospital estates such as Shirley Oaks Hospital, less than half a mile to the east of Addiscombe, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Further education sites such as Croydon College (to the south-west of Addiscombe) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Addiscombe is about 2 miles north-east of Croydon, in Greater London. Looking for construction mastic in Addiscombe? We can help. We work across 764 places in Greater London, large and small. Our London page has more on work in that area, about 8 miles away.

Different surfaces, different methods
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.

What else we do in Addiscombe
Addiscombe: questions and answers
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Can work at a site such as Croydon College fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we’ll set out a timescale with the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What accreditations do you hold?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We confirm any paperwork you need with the quote.
How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Addiscombe can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Tell staff and tenants when we’ll be in
- For older buildings, check the asbestos register before work
Ask for a quote
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email a schedule or drawings with what you know.
Advice
Keeping the joints sound
A few simple habits keep the new joints working:
- Bring the mastic contractor in after the last trades are through
- Ask installers to correct oversized gaps first
- Put any product change through the designer first
- Protect sealed areas from following trades
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. We can confirm the handover information you need when we quote.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out and keeps handover on track.
