Window & Door Openings – Precision Cut by ShellCo in Hertfordshire
Fitted Clean. Sealed Tight. Built to Last
Shellco supplies and fits windows and doors that are built to last, fitted to perfection, and finished with pride. Whether you're after modern anthracite flush frames, traditional white sash, or a custom composite front door — we deliver security, style, and airtight performance in one shot.
Our Fitting Process
1. Site Survey & Sizing
We measure every opening twice — no guesswork. Whether it’s a replacement or new cut-out, we prep the aperture for perfect fitment.
2. Frame & Fixing Prep
Frames are plumbed, packed, levelled and secured using proper fixings and structural sealants. We don’t rely on foam to do the job of bolts.
3. Glazing & Adjustment
Glass is seated on packers, beaded in with precision. Hinges adjusted. Locks aligned. We don’t leave ‘nearly shuts’ behind.
4. Silicone & Final Finish
We tape, gun, and tool smooth silicone lines for that showroom seal — inside and out. Thresholds finished. Trims neat. Area spotless.
