The wet corner is not bad luck. It is a fixable mistake.
Yard drainage in Mystic CT and across the southeastern shoreline. Standing water, soggy lawn, wet basement wall. We find where the water actually stops before anyone digs anything.

Water is never the problem. Where it stops is.
Every property in this county gets the same rain. Only some of them hold it, and the difference is almost always one of six things: ground falling toward the house, downspouts releasing at the wall, a compacted layer eighteen inches down, a brush-choked low edge acting as a dam, an old drain line silted up, or a high water table in that section.
Six problems, six different fixes, wildly different prices. Which is why the expensive way to buy yard drainage is to have somebody dig a trench and hope. A drain set uphill of the actual problem does nothing, and you find that out the following spring.
So nothing gets dug until the site has been read, in the wet if we possibly can. Want the soil science first? Our guide to yard drainage in Connecticut is the long version.
Six symptoms, and what each one is usually telling you.
Almost every yard drainage problem in Mystic CT is one of these six. Find the line that sounds like yours. It will not replace someone standing on the ground, but it will stop you buying the wrong fix.
Most properties need two of these. Almost none needs all six.
The six yard drainage fixes we build, in rough order of what we reach for first. The cheap ones are at the top on purpose, because they are often the ones that work.
Roof water, moved away
A 2,000 square foot roof sheds roughly 1,250 gallons in an inch of rain. Release that beside the wall and no amount of grading keeps the basement dry. Extensions to daylight, or solid pipe to a drywell.
Right when: the wet is near the house. Cheapest fix on this page and often the whole answer.
Regrading and swales
Reshaping the ground so water goes where you decide. The rule is six inches of fall in the first ten feet, and most houses here had it in 1975 and lost it to settling and mulch.
Right when: water sits on the surface or runs the wrong way. See regrading.
French drains
Perforated pipe in washed stone, giving underground water a path out. Cleanouts at every turn so it can still be flushed in twenty years.
Right when: the water is moving under the surface rather than sitting on it.
Curtain drains
The same idea, placed across the uphill side of the problem instead of in it. The only thing that works when the water is not originating on your land.
Right when: you are downhill of a neighbor, a road, or a slope.
Catch basins and dry wells
A grate at the low point, solid pipe, and somewhere legitimate for the water to end up. The outlet is the part that decides whether any of it works.
Right when: there is one defined low spot and somewhere lower to take it.
Clearing the low edge
On wooded lots the dam is often organic. Scrub and years of leaf litter along the low boundary hold water against the lawn. Opening that edge costs less than the pipe would have.
Right when: the wet side of the lawn backs onto overgrowth. See land clearing.
Five things about draining a yard in southeastern Connecticut.
Two of these are about our soil, two are about the law, and the last one is about the calendar.
The water has to go somewhere legal
The most important line on this page. You cannot fix a wet yard by piping it onto the property next door. Concentrating water onto a neighbor turns a drainage job into a dispute you own permanently. Every plan has to answer where the water ends up, and if the honest answer is nowhere good, we say so before you pay for anything.
Near a wetland it is a town matter
Connecticut regulates wetlands through each municipality's own commission, and the regulated area reaches past the wet ground itself. Outletting a drain near one needs a look from the town first. The Connecticut DEEP stormwater guidance is where to start reading.
Ledge and hardpan mean nowhere to soak
Half the towns between Groton and Colchester have ledge within a couple of feet, and glacial till leaves a dense layer water stops at. On that ground a dry well is money wasted. The water has to be moved, not absorbed, so we check what is under you before choosing.
Fabric in clay is how systems die
The commonest thing we find on repair jobs is pipe wrapped in filter fabric buried in clay. The fabric silts up in about three years and what you own is an underground planter. Washed stone, sock pipe only where soils justify it, cleanouts at every turn.
There is a season for this
Late spring through early fall is when the ground works and seed takes, so the lawn recovers in the same season as the dig. Winter freeze and thaw pushes the same job into a longer, dearer version of itself.
If it still holds water, we come back.
Yard drainage is the one trade where you find out months later, in a storm, so the standard has to be the result rather than the installation. If the area we were hired to fix still holds water after a normal rain, we are back on it. Utilities marked through Call Before You Dig, certificate of insurance before work starts, every time.
Take a photo next time it rains.
Seriously. A yard hides all of this the moment it dries out, so that photo is worth more than anything you can say on the phone. A downspout and swale job is two days. A full property regrade runs one to two weeks.

Straight answers about yard drainage in Mystic CT.
What does a French drain cost?
It comes down to length, depth and where the outlet is, and the outlet is the part nobody thinks about. A short run to daylight and a long run that has to get around a septic field are not the same job.
Can you just dig a trench and put a pipe in?
We can, and on plenty of properties it will do nothing. A drain uphill of the real problem, or with no fall, or running to nowhere, is money spent on a hole. That is why we diagnose first.
Will you wreck the lawn?
The trench line gets opened, so there is disturbance. It is backfilled, graded and seeded or sodded, and within a season you cannot see where it went. Working in the growing season is what makes that true.
My neighbor’s water is coming onto my land.
Intercept it at the boundary with a curtain drain and take it somewhere legitimate. What we will not build is a system that pushes the problem to the next property down. That is how a wet lawn becomes a legal matter.
Do I need a permit?
Usually not, well away from wet ground. Near a wetland or watercourse it goes through your town’s Inland Wetlands Commission. If your site looks close, we tell you to check before anything starts.
