About our window mastic in Pilgrims Hatch
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We are often asked to deal with cracked internal joints between frame and plaster and cold air getting in at the frame edge, on aluminium frames, patio & French doors and composite doors.
Around Pilgrims Hatch, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
Whatever the size of the job, it’s backed by our one-year guarantee in Pilgrims Hatch and across Essex.

What affects the cost of window mastic
The quote reflects the job in front of us. We take into account:
- The amount of work
- Which sealant suits the joint
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- Roughly how big the job is
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or drop us an email.
Landlords, agents and businesses in Pilgrims Hatch
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Look round the frames every year or so
- Don’t paint over the silicone
- Repaint timber before it’s bare
- Make sure the drainage slots aren’t blocked
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
How the visit works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a few frames, or a day or more for a whole house. In a smaller place like Pilgrims Hatch, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Let us know about parking restrictions
Getting a quote
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Common problems we fix in Pilgrims Hatch
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Most people get in touch after spotting one of these:
- Hard, cracked sealant around windows
- Draughts coming in around windows and doors
- White mastic on grey or black frames
- Mastic that’s falling out in pieces
For an older house near a landmark such as Saint George's church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- How hidden problems are handled
- Whether you can choose the colour
- How much experience the applicator has
- What preparation is included
Pilgrims Hatch homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Ingatestone Hall (about 4.6 miles north-east) are a reminder that the area around Pilgrims Hatch has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Larchwood Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Brentwood station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Different surfaces, different methods
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Composite doors
Front doors take the weather head on. Those corners get the most care.
