FAQ about paver repairs
When should a paver repair be considered?
As soon as subsidence, joints that open up, cracked stones or an uneven surface appear, it's advisable to act quickly. The earlier you take action, the easier and longer-lasting the repairs will be.
Is it better to repair or completely redo the paving stone?
If the basic structure (foundation and drainage) is still in good condition, a repair is often sufficient to extend the life of the paver. On the other hand, if the problem is widespread or recurrent, a complete overhaul may be more economical in the long term.
How much does a paver repair cost?
Prices vary according to the extent of the problem: replacement of a few stones, correction of localized subsidence or complete overhaul of a section. Each project is unique, and a precise estimate is provided after inspection.
How long does a repair take?
Most residential unistone repairs can be completed in 1 to 3 days, depending on the surface area to be repaired and the complexity of the site.
Do your repairs stand up to Quebec winters?
Yes, we use industry-standard methods (stable foundation, proper compaction, polymer sand) to ensure durability through freeze-thaw cycles.
Do you repair only in Laval?
No. Our team travels to Laval, Montreal and anywhere on the North Shore within a 30 km radius. Depending on the nature of the project, we can also intervene in areas a little further away.
Do you offer a warranty on repairs?
Yes, our paver repairs are covered by a warranty, giving you peace of mind that the work will last.
