Mastic sealing for commercial buildings in Sandhills
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 a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on communal kitchens and washrooms, balcony and threshold joints and shopfronts below residential blocks, and what we’re called in for most is patchy repairs in mismatched sealant and the same joint failures repeated across a portfolio. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Sandhills, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Sandhills, we group work so one trip covers it. Photos of each elevation help us quote accurately.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Quoting for work in Sandhills
These are the things that shape the price:
- Working within restricted access windows
- Whether old sealant has to be cut out first
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- The product your specification calls for
- Clear photographs of the problem areas
- How the joints are reached, and at what height
- Where the site is, with the postcode
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Sandhills, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Send your site hours and access windows
- Let building users know which areas are affected
- Tell us which areas need to stay in use

Advice
Questions about Sandhills
Will you price a mastic programme across our Sandhills portfolio?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photographs and we will give a fixed quote.
Do you work for managing agents with blocks near Witley station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can people stay in the building while you reseal?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
What we’re called out for in Sandhills
The edges of the material itself sometimes break away for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Site and facilities staff are often the first to spot these:
- The same joint failures repeated across a portfolio
- Window mastic that has split and shrunk
- A mix of products and colours from past repairs
- Worn sealant at communal door frames
Churches, halls and community buildings such as Church of All Saints are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Before you book anyone
- How long is the guarantee, and what does it include?
- Whether primer will be used where the manufacturer specifies it
- What level of public liability insurance do they hold?
- Are they CHAS accredited or on Constructionline?

Building owners, agents and FMs in Sandhills
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sandhills can form part of a wider programme.
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Reduce knocks to communal area joints
- Check sealant joints during planned building inspections
- Plan resealing building by building rather than complaint by complaint
- Ask residents or tenants to report leaks and draughts early
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
Block-wide mastic in Sandhills
Rainfall across the South East, Sandhills included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Sandhills is about 35 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
For agents with blocks near Witley station, which lies east of Sandhills, a block-wide mastic programme deals with frames, balconies and entrances in one go. Site managers at schools like King Edward's School Witley can fit frame mastic into the summer works.
