Record the symptoms without disturbing the structure
BRANZ identifies problems such as loose or damaged boards, corroding fixings, springiness and timber decay. Moisture trapped at junctions can contribute to deterioration. These observations can point to a need for investigation, but they do not tell you the complete repair scope from above.
Take photographs from a safe position and describe what you have noticed. Note whether the problem is limited to one area and when it became apparent. If the deck is moving, sagging or visibly damaged, keep people off the affected structure until it has been assessed. Do not pull off a support or remove fixings to see whether they matter.
Look at the cause as well as the damaged material
MBIE’s deck guidance highlights the importance of maintenance, structural connections and keeping water from damaging the building. Concealed deterioration at the house junction can be significant. Cleaning or coating the top surface cannot establish the condition of that connection.
A useful inspection brief asks the builder to distinguish what they can see, what they cannot access and what further checks they recommend. It should also describe the adjoining wall, the ground below the deck and any roof water entering the area. Ask how the proposed repair addresses the conditions around the damaged timber, rather than only its appearance.
When opening up may be needed
Artificial grass, fixed boards, stored furniture and limited ground clearance can hide the parts that need checking. A visual inspection has to record those access limits. If the foundations or connections cannot be assessed, an invasive investigation may be the next step before a final remediation scope is priced.
Agree the investigation area, who clears the deck, what coverings are lifted and how the opened area will be left afterwards. Ask whether temporary protection or restricted access will be needed. The result should explain the findings and what remains uncertain. Opening one area does not automatically describe every support on a large deck.
Compare repair options against the same scope
A local board replacement, new decking over retained framing, a structural repair and a complete rebuild are different proposals. For each option, identify what stays, what is replaced and which existing elements have actually been checked. Include access, waste removal, reinstatement and any required design or approvals in the comparison.
For TrickyBuilds, send a safe overview of the deck, the problem areas and any available records. Tell us if a covering prevents access or if the space underneath is tight. We can agree an initial inspection and discuss whether further investigation is needed. A final repair recommendation follows the evidence available for your deck; it is not chosen from a photograph alone.
Common questions
Will replacing the deck boards fix the problem?
That depends on the cause and condition of the structure below. New boards do not establish that existing framing, supports or house connections are suitable. Ask about an inspection before choosing a surface-only replacement.
Do I need to clear furniture or artificial grass for an inspection?
Tell Caleb what covers the deck and how much access is available. Agree preparation for the particular inspection. An invasive investigation may require furniture to be cleared and coverings or boards lifted; that work needs a separately agreed scope and cost.
Can I keep using a damaged deck while I wait?
If it is moving, sagging, has loose barriers or shows significant damage, keep people off the affected structure and contact Caleb or an appropriate professional for an assessment. A photograph or a booking confirmation does not establish that the deck is safe to use.
What happens after the deck inspection?
The findings explain visible concerns, access limits and recommended next steps. Caleb can discuss a repair quote or a separately scoped investigation where more evidence is needed. Any remediation scope follows what was established rather than an assumption about concealed work.

From an inspection to a repair scope
Use the TrickyBuilds deck and pergola inspection enquiry for a condition assessment. Send the address, safe photographs, the structure you want checked and any access limits. The agreed visual scope and current fee are explained on the inspection page. If opening up is recommended, we agree the preparation, cost and investigation area first. Remediation is then quoted from the findings; a visual report does not promise that concealed foundations are sound.
