Expert Deck Builders in Lexington, MA

Lexington homeowners invest in properties they plan to keep. That often means inheriting decks that have weathered 15 or 20 Massachusetts winters. The symptoms are familiar: boards that catch bare feet, railings loose enough to worry about, posts that feel soft when you push. Pressure-treated lumber reaches its limit eventually. We have been building and replacing decks for 27 years and recognize the signs every spring. Composite materials now offer a real alternative for homeowners tired of annual staining and constant upkeep. We can walk you through what makes sense.

Why Lexington Homeowners Choose Faithful Build for Deck Building

We know the permit process at Lexington's Building Department and handle the online application, documentation, and inspector coordination. Many properties here border conservation land or sit near wetland areas, which means the Conservation Commission may need to review your project. We check setbacks, drainage requirements, and any environmental considerations before providing numbers. Elevated decks need engineering. Ground-level builds need proper airflow underneath. That upfront preparation results in accurate quotes and projects that stay on schedule.

About Our Deck Building Services in Lexington

A deck expands how you live in your home. In Lexington, where properties often back up to wooded lots or conservation trails, outdoor space becomes an extension of daily life. Coffee in the morning before work. Dinner outside on summer evenings. Weekend gatherings that spill out from the kitchen. These moments happen when the space invites them.

Massachusetts weather tests everything built outdoors. Between December and March, temperatures cross freezing dozens of times. Water penetrates small gaps, freezes, expands, and works fasteners loose. By April, boards have shifted and connections have weakened. Summer brings humidity that feeds mold growth in shaded areas. UV exposure degrades finishes on south and west-facing surfaces. Heavy snow loads during nor'easters stress the entire structure. A deck built without these conditions in mind will fail sooner than it should.

Material selection determines both how long your deck lasts and how much time you spend maintaining it. Pressure-treated lumber costs $15-25 per square foot installed and handles the elements adequately when maintained. That maintenance is real work: power washing, sanding, staining every two to three years. Skip a year and the wood grays, cracks, and eventually splinters. Cedar runs $25-35 per square foot and offers natural rot resistance with better aesthetics, but still needs regular sealing to keep its color.

Composite decking has changed the calculation for homeowners who value their time. Trex and TimberTech products cost $40-65 per square foot installed, but the maintenance equation is different. No staining, ever. No sanding splinters every spring. No worrying about rot when the snow finally melts. The material handles freeze-thaw cycles better than wood because it does not absorb water the same way. Over 20 years, composite typically costs less than wood when you factor in all those hours and all those cans of stain. For Lexington homeowners who plan to stay in their homes, which is most of them, composite makes financial sense.

Our process begins with walking your property. We look at grade changes, drainage patterns, mature trees to protect, and how the deck will attach to your house. The ledger connection is structurally critical and we plan it thoroughly. From there, we develop a design that fits your space, your budget, and how you actually want to use it. Simple platforms work for some. Multi-level layouts with built-in seating, pergolas for shade, or integrated lighting work for others. Hot tub platforms, outdoor kitchen framing, privacy screens. We build what makes sense for your situation.

Permitting is part of every deck project. Lexington uses an online system that streamlines the process, but the requirements remain serious. We handle the application, pay fees, upload documentation, and schedule inspections. Projects near wetlands or conservation land may require Conservation Commission review, and we coordinate that as well. You should not have to navigate bureaucracy to improve your own backyard. We build the timeline into the project schedule so there are no surprises.

Every deck we build includes manufacturer warranties on materials and our workmanship warranty on installation. Most failures trace to how a deck was built rather than what materials were used. Footings below the 48-inch frost line, properly sized framing for actual loads including snow, correct fasteners for outdoor exposure, careful flashing at the ledger. These details determine whether your deck lasts 15 years or 40.

Twenty-seven years under the same family ownership. Crews who show up when scheduled, protect your landscaping, and clean up at the end of each day. That consistency matters in communities where people stay, where neighbors know each other, and where reputation spreads by word of mouth.

Frequently Asked Questions

Deck Building in Lexington: Your Questions Answered

Most deck projects in Lexington run between $12,000 and $50,000, depending on size, materials, and complexity. Here is how the numbers break down: A 300 square foot pressure-treated wood deck typically costs $12,000-20,000 installed. The same size deck with Trex or TimberTech composite runs $25,000-40,000. Premium PVC decking or exotic hardwoods like Ipe push costs to $35,000-50,000 or higher. These prices include design, framing, decking, and standard railings. Common add-ons affect the total: stairs add $20-45 per step, built-in lighting runs $300-1,500, and pergolas or shade structures add $3,000-10,000 or more. Per square foot, expect $15-25 for pressure-treated wood, $40-65 for composite (Trex, TimberTech), and $45-70 for premium PVC materials. Labor typically runs $15-35 per square foot on top of materials. We do a thorough on-site assessment, check engineering requirements, and factor in permitting fees to provide accurate written quotes with line items so you see exactly where every dollar goes.
In most Massachusetts towns including Lexington, you need a permit for almost any deck project. The common exception is freestanding decks that are less than 200 square feet AND less than 30 inches above grade at any point. Even then, local requirements can vary. The 30-inch rule is the key threshold. Once any part of your deck exceeds 30 inches above the ground, you need a permit for the entire structure, plus railings become mandatory. Attached decks almost always require permits because they connect to your home's structure. The ledger board attachment is a critical structural element that building departments want inspected. Our recommendation: always pull permits. The cost is minimal compared to the project total, and unpermitted work creates problems when you sell your home. We handle all permitting through Lexington's Building Department so you do not need to figure out the requirements yourself.
Late spring through early fall offers the best conditions for deck building in Massachusetts. April through October typically provides dry weather and moderate temperatures ideal for construction. The practical answer depends on your timeline: Spring (April-May): Good building weather, but contractors book up fast. If you want a deck ready for summer entertaining, contact us in January or February to get on the schedule. Summer (June-August): Prime deck season. Warm weather, long days, consistent conditions. Also the busiest time with extended lead times. Fall (September-October): Often the best value. Weather remains good, schedules open up after the summer rush. Your deck will be ready for next spring. Winter (November-March): Challenging but possible for some projects. Frost and frozen ground complicate footings. Snow delays work. Composite materials have temperature minimums for installation. The earlier you start planning, the more flexibility you have with timing. We build year-round and adapt to conditions.
The decking material itself is typically the largest single cost, running 30-40% of your total budget. But several factors compete for your dollars: Decking boards: The surface you walk on. Pressure-treated runs $3-6 per square foot for materials alone. Composite jumps to $5-13 per square foot. Premium PVC and exotic hardwoods hit $15-30 per square foot. Framing and structure: The joists, beams, and posts that support everything. This runs 15-25% of total cost. Elevated decks cost more because they need longer posts, additional bracing, and often engineering. Labor: Typically 35-50% of the project total. Complex designs, multi-level layouts, and difficult site conditions increase labor costs significantly. Railings: Often underestimated. Basic wood railings run $20-35 per linear foot installed. Cable or glass railings jump to $100-200 per linear foot. Stairs: Each step adds $20-45 to the project. A long staircase from an elevated deck can easily add $1,500-3,000. The smartest way to control costs: decide on your priorities early. Premium decking with basic railings? Or budget decking with upgraded features? We help you allocate your budget where it matters most to you.
In Massachusetts, railings are required when any part of your deck surface is more than 30 inches above the ground below. This is per the Massachusetts State Building Code, which follows the International Residential Code. Once railings are required, they must be at least 36 inches high, measured from the deck surface to the top of the rail. Some towns require 42 inches, so we verify local requirements for every project. Railing requirements also apply to stairs. Any stairway with four or more risers needs a graspable handrail on at least one side. Open sides of stairs more than 30 inches above grade need guardrails. Baluster spacing matters too. The gap between balusters cannot exceed 4 inches. This prevents children from slipping through. We design and build every deck to meet or exceed code requirements. Inspectors check railing height and baluster spacing during final inspection, and we make sure everything passes the first time.
The ideal deck height depends on your home's layout and how you will access the space. Most decks fall into three categories: Ground-level (under 12 inches): Sits just above grade. No stairs needed if you step directly onto lawn. Simpler construction, lower cost, no railings required. Good for flat yards and casual outdoor spaces. Standard height (12-30 inches): Common for homes with a step down from a back door. May or may not require railings depending on exact height. One or two steps down to yard. Elevated (30+ inches): Required when the entry door is well above grade, common with walkout basements or sloped lots. Requires railings, often needs stairs, and may require engineering for the supporting structure. The door threshold usually dictates your deck height. The deck surface should sit about 1-4 inches below the door threshold to prevent water and snow from entering the house, while still allowing the door to swing open freely. We assess your site and door height during the initial consultation. The right height balances code requirements, accessibility, and how you want to use the space.
We see the same problems when we tear out old decks or fix DIY projects gone wrong. Here is what goes wrong and how we avoid it: Inadequate footings: Footings that do not extend below the frost line (48 inches in Massachusetts) heave and shift. We dig proper footings every time. Undersized framing: Joists spaced too far apart or beams that are too small cause bounce and eventual sag. We size framing for the actual loads, including snow loads. Poor ledger attachment: The ledger board connects your deck to your house. Improper flashing or inadequate fasteners cause water damage and structural failure. This is the number one cause of deck collapses. We use proper flashing and lag bolts into the rim joist or through-bolts when required. Wrong fasteners: Using interior screws or nails that rust. We use stainless steel or coated fasteners rated for pressure-treated lumber and outdoor exposure. No gap between boards: Boards need room to expand and drain. We space boards properly so water does not pool and debris does not trap moisture. Skipping permits: Unpermitted decks create liability and complicate home sales. We pull permits on every project. These are not minor details. They determine whether your deck lasts 10 years or 30.
We provide two types of warranty coverage on every deck project: Workmanship warranty: We stand behind our installation. If something fails due to how we built it, we fix it. This covers structural issues, fastener problems, railing stability, and installation defects. The specifics depend on the project scope and are detailed in your contract. Manufacturer warranties: The decking materials carry their own warranties: Trex: 25-year limited residential warranty on boards. Transcend line includes fade and stain warranty. TimberTech: 25-50 year structural warranty depending on product line. AZEK PVC carries 50-year warranty with lifetime fade and stain coverage. Pressure-treated lumber: Limited treatment warranty, typically 10-20 years against rot and insect damage. Cedar: No standard warranty. Natural material durability depends on maintenance. We provide warranty documentation for all materials at project completion. If you ever have an issue, contact us first. We will determine whether it is a workmanship matter we handle directly or a manufacturer warranty claim we help you navigate. Most deck failures trace to installation problems, not material defects. Our workmanship warranty exists because we are confident in how we build.
