Frequently Asked Questions
Do I need a permit for excavation in Newmarket?
Yes for foundations, additions, pools, and most retaining walls. Properties near the Holland River watershed may also require LSRCA approval.
How long does a basement excavation take in Newmarket?
2 to 4 days for a standard residential basement. Larger custom builds run 4 to 6 days. Newmarket clay holds water and slows things in wet seasons.
Can you handle drainage problems in Newmarket backyards?
Yes. Flat Newmarket lots near the Holland River often pond after heavy rain. We assess grade, install swales or drainage tile, and re-grade to move water away. Typical fix runs 1 to 3 days.
Do you work with Newmarket builders on new home projects?
Yes. We’ve worked with several Newmarket-area custom builders. References available on request.
What’s the best time of year for excavation in Newmarket?
Late spring through early fall is ideal. We do winter work but it costs more due to slower digging and frost-blanket use.
Newmarket is a short Yonge Street run from Richmond Hill, so we keep our equipment route flexible between the two.
