Tips and FAQ

Here are several tips how to negotiate a lower cost of retaining wall with a contractor:
1) If you have certain store discounts, credits, or credit card points that you want to use you can opt to buy retaining wall blocks yourself and have contractor only provide the installation. Note that when buying wall blocks, in addition to a block price you need to account for delivery and skid deposit. Most stone yards provide delivery, and they will unload skids of wall blocks right on your front yard with a truck-mounted piggyback forklifts. Also, stone yards usually take $50-$70 deposit for every skid which you get back when you return skids back to stone yard.

2) Some unethical ways that we do not endorse but which is quite popular is to pay cash for project as opposed to paying by cheque. In this case most contractors will still want you to pay for materials by cheque. While you may save some money this way it is harder to enforce warranty for the installation work should anything go wrong with the retaining wall such as alignment or stone cracks. Without a trail of cheque, invoice, and contract you are relying on a contractor’s integrity to provide warranty service repairs.
3) Construction contractors may quote different prices based on how busy they are (i.e., how many projects they have lined up). This usually varies greatly from one company to another but on average landscaping contractors have smaller backlog of projects at the beginning of the season (March - May) and in the middle of the season (July - August). Asking for quotes during these months may nail you a better price.
4) Homeowners can also save on retaining wall blocks if they follow the deals from stone yards. For example, sometimes Beaver Valley stone yard posts deals on their Instagram feed and website for wall blocks that go for discounted prices.

1) Get quotes from 2-3 contactors. You may be tempted to go with the contractor who got recommended to you by a friend or contractor who did a good job at a project down the street. While referral comes with certain promise for quality you may be overpaying greatly when selecting a contractor this way. When contractors get clients from referral or word of mouth, they tend to quote a higher than usual price because a) they know their reputation is working in their favor. b) they know a client is likely not shopping around.
2) Don't put too much trust in reviews online. Large companies like Google and Facebook only relatively recently started enforcing major fight on fake reviews. Smaller companies tend to be slower at this because they neither have the resources nor have an incentive to tackle fake reviews ( often their business model depends on fees that they charge to contractors hence they are hesitant to remove the fake good reviews from their platforms ).
3) While selecting the most affordable contractor it’s better to be weary of the ones that quote prices below general market price. Firstly, inexperienced contractors may do a bad quality work. Bad retaining wall alignment or uneven stone cuts are only some of the examples of bad quality work. While some things are easy to catch right away, others such as poorly compacted grading may not present themselves until couple of years later. Secondly, small companies or the ones that haven’t been in business for long may not live long enough to fulfill any possible warranty incidents that may arise in future. Unfortunately, some construction companies go out of business and if the alignment of your retaining wall becomes uneven the company that’s out of business will not get fixed it as promised.
4) Ask contractor about the warranty that they are offering for the installation. 2–3-year warranty is the general norm among good quality contractors.
5) Check out contractor’s portfolio and pictures of previous projects. If any of their retaining wall were built at the front yard you can even drive around and check them in person. Ask if contractor has done commercial projects before. If they have usually it’s a good sign of their expertise.
6) When it comes to payments the good approach is to break it into 2 – 3 installments that come due as project moves along. Every contractor does things different here, but a good rule of thumb is split payments into 3 parts:
Contractor brough team and equipment on site and is ready to start work – 1st payment is due.
Middle of the project is done – excavation, grading, and compacting is done – 2nd payment is due.
Project is complete – garbage/bin is taken out. - 3rd payment is due
Also, it is normal for contractors to take small deposit of $500 after the estimate in order to put your project in their list of future work.
