Drainage is crucial to living plants and hardscapes alike. With poor drainage water can be diverted away from plants that need it leading to yellowing lawns and dying flower beds, but will pool in others .You may or may not see that pooling since the water could be collecting below the level of the top soil but the end result is saturation that will also kill off the roots of plants in that area as well. For hardscapes poor drainage not only means that there are standing pockets of water that can expand with freezing temperatures or warmth and that will push hardscapes out of shape. Water movement under the soil can lead to uneven pathways or patios and create trip hazards. Which is why we take your yard drainage seriously and propose a number of options.
It's gonna rain, but when it does that water shouldn't stay on the surface of your ground and if you're seeing muddy patches then that means you've got poor drainage. If at any point rainfall overcomes the ability of the soil to suck it up then the grade of your yard should be such that water runs into swales and is taken away to the curb or storm drain. If it doesn't then you may need us to check out your run off angles and grades and correct them so that you don't have standing water.
Hard pan is a dense layer of soil that sits below the top soil and causes all sorts of drainage problems. That could be clay or it could be compacted soil but either way it naturally catches rainwater and holds it just below your lawns, plants, or hardscapes. Combine that with a high water table and you will have serious drainage problems that may not even be visible but will affect your surface soils and your hardscapes and driveways.
Dry wells are effectively a ditch dug vertically into the ground and walled like a well shaft with permeable cement and brick walls. That allows water in the soil, even fairly deep down, to drain into the shaft and collect at the bottom where it can be safely steered away to storm drains or allowed to diffuse. Deciding what depth to excavate to is a skilled task based on the soil analysis and likely rainfall but when properly done by the experts (like us) the result is a reliable drainage solution that doesn't require pumps or maintenance.
French drains are a tried and trusted solution for most yards and are simple and straightforward but still benefit from an expert eye to plan where they should run and at what depth. The heart of the French drain is a ditch lined with landscape fabric and sand patches and a porous pipe which helps not only run the water away but spread it as it goes so that doesn't pool somewhere else. French drains are mechanically simple but still require a professional eye to site them properly to deal with your drainage issues
