The Summer the Hendersons Almost Skipped the Fence

(And Why Their Dog Is Glad They Didn't)

A February Dream

Every February in North Andover, a certain kind of madness sets in. The snowbanks are gray, the driveway has been shoveled eleven times, and somewhere around the third nor'easter, perfectly sensible people start dreaming about swimming pools.

Mark and Julie Henderson caught the fever hard. By Valentine's Day, their kitchen table was buried under pool brochures, and Mark had already picked out a giant inflatable flamingo. He had a whole vision: him, the flamingo, a cold drink, and absolutely nothing to do on a Saturday in July.

Julie's vision was a little different. Hers included their three-year-old daughter, Lily, who has never met a closed door she didn't want to open, and Biscuit, their golden retriever, who firmly believes every body of water on earth belongs to him personally. Puddles, bathtubs, the neighbor's koi pond. All Biscuit's.

"We'll need to think about safety," Julie said.

"We'll just keep an eye on things," Mark said.

Julie gave him the look. The same look that ended his plans for a backyard zip line and a pet snake named Kevin. Mark went quiet and pretended to study a brochure about filters.

The Picket Fence That Wasn't

In April, the pool installer came out to finalize the plans. Mark proudly pointed to the old picket fence running along the back of the property.

"So we're all set on the fence," he said.

The installer squinted at it the way a mechanic looks at a car making a funny noise. "That one's not going to pass," he said. "You'll need a proper pool barrier before the town signs off."

It turns out Massachusetts takes this seriously. Pool barriers fall under the state building code, 780 CMR, and while you can often put up a regular backyard fence without a building permit, a pool barrier always needs one. The rules apply to any pool holding more than 24 inches of water: in-ground, above-ground, and even those big inflatable pools from the home improvement store.

That night, after Lily was asleep, Julie read something that stopped the joking for a minute. According to the CDC, a fence that fully surrounds a pool can reduce the risk of drowning by 83 percent. These accidents happen fast and quietly, often when a small child slips outside while an adult is distracted for just a moment.

Mark looked out the window at the picket fence, with the missing slat Biscuit had "renovated" last fall. "Okay," he said. "We're doing this right."

Mark Falls Down the Rabbit Hole

Mark, being Mark, decided to become an expert. He spent an entire Saturday night reading building codes, and by Sunday dinner he was talking like a man who had seen things.

"Did you know," he announced, passing the potatoes, "that no opening in the fence can let a four-inch sphere through?"

"A what?" Julie said.

"A sphere. A ball. Four inches."

"I want a sphere," said Lily.

Biscuit, sensing that the word "ball" had entered the conversation, fetched his tennis ball and chewed it aggressively under the table in solidarity.

Mark carried on. The fence had to be at least 48 inches tall, measured from the finished ground. Lattice-style fences had even tighter rules, with diagonal gaps no wider than 1¾ inches, so little feet couldn't use them as a ladder. And on top of the state rules, individual towns could add requirements of their own.

He set down his fork. "I think," he said, with the solemnity of a man admitting defeat, "we need a professional."

Julie had been thinking that since February.

Enter MValley Fence

Julie called MValley Fence right there in North Andover at 978-689-2125, and by the end of the week an estimator was walking their backyard with a tape measure and a clipboard. Biscuit followed him every step of the way, supervising.

What the Hendersons appreciated most was that he turned all the code talk into plain English. He didn't just measure; he noticed things. The yard sloped toward the back corner, which meant the fence had to meet the height requirement at every point, not just on the flat part. And the kitchen door opened almost directly toward where the pool would go, which is exactly the kind of route a curious three-year-old would discover. He walked them through their options for that, too.

Then came the fun part: picking a style. Mark wanted something that didn't make the backyard look like a prison yard. Julie wanted something that would still look good in ten years. They talked through aluminum, vinyl, and ornamental options and landed on a clean black aluminum fence that let them see the pool from the patio while keeping it completely enclosed.

"And what about the permit?" Mark asked, a little too hopefully.

The estimator smiled and explained how the process would go. He had clearly met a Mark before.

Permanent or Removable?

Before he left, Julie asked about something she'd been wondering. A friend in Andover had one of those mesh pool fences that slides in and out of sleeves set into the pool deck. "Should we just do one of those instead?"

The estimator explained the difference. A permanent fence is the backbone. It's a sturdy barrier that encloses the whole pool area, stands up to New England winters, and is there every single day without anyone having to remember a thing. A removable mesh fence sits closer to the water's edge and can come down when it isn't needed, like when only adults are around or at the end of the season. It makes a great second layer of protection, he said, but whether a removable fence alone would satisfy the inspector depends on the town and the setup. For most families, the permanent fence comes first.

The Hendersons went with the permanent fence. It was what the town needed, it gave them real peace of mind, and honestly, Mark was already worn out from the sphere research.

The estimator mentioned that a removable fence could always be added later. Julie filed that away.

The Gate: The Unsung Hero

If any part of a pool fence deserves a standing ovation, it's the gate. Most barrier problems happen at the gate, because people are people. They carry coolers. They're holding a toddler. They forget.

So the rules are specific. A walk-through gate has to swing outward, away from the pool. It has to close by itself and latch by itself, with no relying on anyone's memory. And if the latch release is lower than 54 inches off the ground, it has to be on the pool side of the gate, at least three inches below the top, with no gap bigger than half an inch within 18 inches of the latch. In other words, a small hand can't reach through and pop it open.

Once the gate was installed, Mark tested it. Then he tested it again. Around the fortieth time, Julie asked if he and the gate needed some privacy.

Lily gave it a try, too. She pushed. She pulled. She stood on her tiptoes. The gate did not budge, and she looked deeply offended.

Everyone else was thrilled.

Installation Day and the Big Inspection

The MValley crew showed up on time, worked clean, and left the yard looking better than they found it. The posts went in straight, the slope was handled so the fence stayed at the proper height all the way around, and the finished fence looked like it had always been there.

"It looks like it came with the house," Julie said.

The town inspector came, measured, checked the gate (Mark hovered nearby, ready to demonstrate), and signed off. Mark felt a deep and completely unearned pride in a fence he had not built.

One Summer Later

That July, it all came together. There was a Fourth of July cookout, neighbors in the yard, burgers on the grill, and kids everywhere. Every time someone walked through the gate, it swung shut behind them with a satisfying click. Mark finally got his flamingo moment. And Biscuit, after one very dramatic afternoon of staring at the gate, accepted that the pool was not, in fact, his.

Then, in the fall, came big news. Julie's sister was moving to Methuen with her twin toddlers, and the Henderson backyard was about to get a lot busier. Julie remembered what the estimator had said and called MValley Fence again. This time they added a removable mesh fence right around the pool. On busy family weekends it's up, so the little ones can run around the yard without getting anywhere near the water. When it's just the grown-ups, it comes down in a few minutes.

Two layers of protection, and a lot less worry. Mark calls it "the belt-and-suspenders plan," and for once, Julie lets him take the credit.

Your Turn

A pool should be the place where you finally relax, not the place you're constantly watching over your shoulder. Getting the fence right, from the height and the gaps to the gate and the permit, is what makes that possible.

If you're planning a new pool, thinking about adding a removable fence for extra protection, or just not sure your current fence would pass inspection, call MValley Fence at 978-689-2125. From their home base in North Andover, they install pool safety fences for homeowners in Lawrence, Andover, Methuen, Haverhill, Amesbury, Merrimack, Lowell, Dracut, Tewksbury, and Tyngsboro.
