Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Mastic sealing in Shillington
Managing agents and housing associations typically need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints, and the failures we are asked to look at most are the same joint failures repeated across a portfolio and communal area joints that look neglected. One point of contact handles commercial sealant work in Shillington from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around smaller places like Shillington, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Shillington may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Send your site hours and access windows
- Explain the parking and delivery arrangements
- Flag any permit to work we will need

Nearby places to Shillington
Also in Shillington
Do you need mastic sealing in Shillington?
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Site and facilities staff are often the first to spot these:
- Damp patches beside frames
- Complaints coming in block by block
- Worn sealant at communal door frames
- Open joints in brickwork or panels
Landlords with units on estates such as Manor Farm Business Park (1.7 miles south-west of Shillington) can bring frame, door and external mastic across several units into one programme.
Questions to ask before you book
- Their public liability cover
- Whether old or failed sealant will be cut out, not overlaid
- How they handle RAMS and site documents
- What the guarantee covers, and for how long
Your questions answered
Can you quote for a block close to Arlesey station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Shillington off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

For owners and agents in Shillington
Central London is about 36 miles from Shillington. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Shillington sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
If you’re responsible for a building such as Church of All Saints, frame and door mastic needs the same attention as any other property. If you look after a block within reach of Arlesey station, which lies north-east of Shillington, frame and balcony mastic can be renewed on one programme.

Aftercare for building managers
After handover, these steps help:
- Reduce knocks to communal area joints
- Include mastic in your cyclical inspections
- Ask residents or tenants to report leaks and draughts early
- Have the asbestos survey to hand for older buildings
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
Why deal with it now?
Failed perimeter mastic lets cold air in around frames and the windows usually get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like Shillington. Send photographs of each area and we’ll quote for the lot.
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.
