Northern Ireland's specialist wall tie surveyor
Cavity Wall Tie Checks for Northern Ireland Homes
Stepped cracks running along the mortar lines, brickwork that seems to bow outwards or window sills that have started to tilt can all hint that the metal ties holding a cavity wall together are corroding. Wall Tie Survey NI takes bookings for wall tie surveys at a set price across the six counties. Book the visit, tell us what you have seen on the outside of the house, and a local specialist will be in touch to arrange a time.
About Wall Tie Survey NI
Looking inside the cavity before anyone talks about repairs
Reading the brickwork first
The specialist starts outside, noting horizontal cracks in the bed joints, bulges and any movement around openings, since these patterns help separate tie trouble from other causes.
A look at the ties themselves
Ties are located along each wall and, where a closer view is needed, a small drilled hole lets the specialist inspect a sample inside the cavity for rust and expansion.
Replacement only when it fits
Some ties show surface rust and still have years left. The specialist explains whether remedial ties are needed now, later or not at all, and how big the job would be.
Findings you can pass on
After the visit you receive a written report listing what was found on each elevation and the suggested next step, ready to share with a seller, solicitor or lender.
From Belfast to Fermanagh
Bookings come in from older cavity-built semis, coastal properties exposed to salty air and rural farmhouses in every county, so a specialist familiar with local building types can attend.
why your wall tie survey differs
Why Northern Ireland walls need a local eye
Wind-driven rain off the Atlantic and Irish Sea, plus early cavity construction, speeds up tie corrosion; a specialist working in Northern Ireland knows which elevations to check first.

Insurance cases
When a lender, insurer or buyer asks about the ties
A homebuyer report or mortgage valuation will sometimes flag cracking that could point to tie corrosion and then recommend further investigation. If that note is what prompted your booking, include the wording with your details so the specialist knows which elevations and questions the lender or your solicitor wants covered.
Insurers and lenders each set their own requirements, so it is worth confirming with them what paperwork they expect. Where remedial wall tie replacement is later carried out, the specialist may issue a certificate for that work, which you can file with the deeds and pass to a future buyer.
What to expect
From booking to the written tie report
- 1
Book the wall tie survey
Choose the wall tie survey option and book it at the set price shown. Add the property address, roughly when the house was built and whether it is detached, semi or terraced, since tie type and spacing changed over the decades.

Note the warning signs
Tell us what made you look closer: stepped or horizontal cracking in the mortar, a bulge in the gable, window or door heads that seem to have lifted, or a mention in a buyer's report. Photos of the affected elevations are a real help.

Visit date and access
A local specialist will be in touch to arrange a time and ask about access to each outside wall, including any rear lanes, conservatories or sheds built against the brickwork.
