Radon Testing and Mitigation in Hamilton
Hamilton's century homes are the reason a phone estimate here is nearly meaningless. What the walls turn out to be genuinely changes the price.
What drives radon levels in Hamilton
Stone foundations, rubble walls, dirt-floor sections, and additions layered on across generations are all common in this housing stock. Hollow block is the detail that changes the whole approach: its cores form a continuous cavity running from footing to sill, and that cavity acts as its own route for soil gas, entirely separate from anything happening under the floor. A design aimed only at the slab leaves that path completely open.
What a fair quote looks like here
Find out whether the quote covers wall depressurization in addition to sub-slab work, because in block construction those are two different interventions with two different costs. Any figure produced without someone examining the foundation is a guess, and on a house of this age the honest answer during a first visit is often a range plus an explanation of what would move it. Ask also whether a return visit for sealing is priced in, since rubble and stone rarely seal completely on the first attempt.
Timing the work in Hamilton
These are the properties most likely to need a second visit, and a contractor who tells you that at the outset is being straight with you rather than padding the job. Dirt-floor sections need membrane laid before any other work is worth doing. Owners of historic homes planning restoration work should sequence radon early, while foundations are accessible and before finishes go back in.
